Advantages of Using JavaScript in 2022

November 11, 2022 Comments Off Roxana read

JavaScript code snippets can be processed on the client side rather than the server, which lessens the strain on the server. The JavaScript codes on a webpage are processed using the user’s system resources. This server-side processing enables the majority of functionality. It drastically shortens and speeds up the process of creating animations and other associated elements, resulting in a fluid user experience.

Effective Frameworks

Numerous potent frameworks created on JavaScript, which has become one of the most extensively utilized languages, have ready-to-use and readily accessible code. These programs are simple to comprehend and can be quickly debugged. In 2022, JavaScript frameworks will include new capabilities that boost efficiency and cut down on time.

Because JavaScript is supported by the majority of browsers, any browser can easily comprehend and interpret JavaScript code. Simply opening your browser will start the process of changing different web page components. Considering that it is a technology that is easily accessible and freely available, no installation or configuration is required.

Amazing Versatility

JavaScript may be used in a wide variety of applications and gets along well with other languages. There are currently several ways to use JavaScript on Node.js servers. If you bootstrap Node.js with Express, make use of a document database like MongoDB, and use JavaScript on the front end for clients, it is feasible to develop a complete JavaScript app from front to back using only JavaScript.

Event-based Programming Features

Because JavaScript is an event-based programming language, it runs different code segments whenever a user clicks a button or moves the mouse. None of the code is initialized at the time the webpage loads. This guarantees that additional features are presented without latency and that your website runs swiftly.

Write server-side code

Using a cross-platform runtime engine like Node.js, web developers can write JavaScript server-side code. Node.js may be used to create a cross-platform server-side runtime environment. It also efficiently executes JavaScript code using the Google V8 JavaScript engine. Because Node.js has integrated libraries, programmers may operate web applications more effectively and rely less on external web servers.

Why Are Super Apps so Powerful?

November 11, 2022 Comments Off Roxana read

Millions of users use super apps to pay bills, book hotels, plan trips, and shop. This is why we are curious about these apps, what makes them so popular, and if these apps will also dominate the West in the future.

An overview of super apps

An app that offers multiple features and services within a single ecosystem is called a super app. As a self-contained platform for online communication and commerce, a super-app should include payments and transaction processing. For example, a Facebook account gives you access to its messaging app, video chat service, marketplace, and job posting features.

Highlights of the super apps:

Shortening the customer journey by addressing multiple pain points simultaneously
Easy-to-use tool for users
One feature that makes one super app stand out from the rest.
The ability to make payments directly from the app
Feature-rich vertical architecture

Super apps’ advantages and disadvantages

All-in-one app with so many features

Pros

When you consider that all of the services can be accessed from one app, there is some level of convenience. All the things you need for messaging, art, and pizza orders can be done in one place instead of using messenger, Instagram, or Uber.

Cons

Users may find it difficult to manage all these services if they do not have them all in one place. Individual rights and privacy are very significant to western customers. Some people might not be willing to keep a bunch of apps they don’t use.

Data tracking

Pros

Using super apps can also provide a massive amount of data. You can track the trends and behavior of groups and individuals alike when you have all of your users in one app.

Cons

Some users might not be comfortable with handing over all their data to just one company, even though super apps aren’t necessarily more unsafe than traditional apps.

Keeping it up to date

Cons

The size of super apps is enormous. Consequently, their code libraries are large, as well. You’ll have to expand the code every time you want to integrate another app into the ecosystem so that it’s in line with all the other apps. One change to the cheeseburger banner within the food delivery app can ruin your super-mega-app.

What do you need to know about the technology behind super apps?

The most challenging part of making sure your features improve the customer experience is to make sure they work. After a while, WeChat became so popular in China that it was on almost every smartphone. Super apps are more successful the easier it is to add new features, and the more audience you can reach, the better.

Final thoughts

There seem to be no escaping super apps in the future. In light of the ever-improving app development landscape, it appears that multifunctional, high-quality apps are less and less far away.

Creating an app that serves the consumer without being intrusive is always the biggest challenge. Nevertheless, the issue keeps being resolved year after year.

Future of JavaScript In 2022: What To Expect Next?

November 10, 2022 Comments Off Roxana read

Future of JavaScript in 2022: Overview

The IT sector uses a plethora of programming languages. Even while most programming languages have a similar syntax, they all have their own special qualities. Different programming languages are utilized for developing an application’s front end and back end. Some of them may, however, be used for both purposes.

One such language that provides the most flexible features to programmers is JavaScript, which continues to be the buzzword in the world of Web development and computer languages. According to a new survey by Statista, JavaScript is among the languages that are most often used worldwide. Just over 55% of respondents said they utilized HTML/CSS, while more than 60% said they used JavaScript.

Due to the language’s rapid development, its importance has increased over time, and in 2022, JavaScript will be the most relevant and in-demand programming language.

What is JavaScript?

Along with HTML, JavaScript (JS) is an object scripting language that is used on websites. Its support, which enables the execution of dynamic content on a webpage, is used by all web browsers. In one way or another, JavaScript is used in the majority of functions and applications that make the Internet such a vital part of contemporary life.

The key to JavaScript’s widespread success was the inclusion of web browsers, and JS stands apart because it renders all of its special functionality in the client’s browser rather than on the site’s server.

JavaScript can execute widgets, Flash programs, PDF files, and other external apps in addition to supporting web pages. JavaScript is currently required by all online technologies since it has grown so essential to the web business and is practically indispensable.

Both an object-oriented and a procedural language, JavaScript, may be used. Modules, namespaces, anonymous (lambda) functions, prototypal inheritance, and metaprogramming are some of the complex features it offers. JavaScript allows for the creation of whole applications like Gmail and Google Maps.

JavaScript in the past years

Early in the 1990s was a critical time for the development of the Internet. The browser market saw competition between Microsoft and Netscape. Programmer at Netscape Brandan Eich created the programming language that is now known as JavaScript in September 1995.

When Netscape saw the need for efficient management and source control of JavaScript in 1997, the European Computer Manufacturers’ Association (ECMA) was given the responsibility of creating the specifications for this specific language.

Three versions of JavaScript were given by ECMA between 1997 and 1999; however, a fourth version was not considered because of differences in the language’s characteristics. In 2005, JavaScript saw a considerable improvement thanks to the introduction of Ajax, a cutting-edge technological package.

Ajax enabled web pages to perform like native desktop apps, greatly enhancing the user experience. It almost seemed as though this release gave JavaScript new life.

The world has advanced technologically thanks to initiatives like Node.js, V8, and others that have made it possible for JavaScript to be utilized in applications it was never intended for. It is about to advance thanks to Asm.js and WebAssembly. And with so many ideas in various stages of development, JavaScript’s future appears to be as bright as ever.

Despite a long and difficult trip, JavaScript is still one of the most widely used languages in 2022.

What to look forward to in ECMAScript 2022?

The computer language JavaScript is always expanding, and in 2022, one may anticipate the following modifications in JavaScript as part of the language’s next yearly update to ECMAScript, which formally standardizes it.

Top-Level Await

Since ECMAScript 2017, asynchronous functions have been accessible in JavaScript, however, programmers must explicitly declare an asynchronous function. That feature is essential for integrating WebAssembly modules with JS since the new module structure in Top-level Await can assist in managing all these asynchronous operations.

Private Fields

Normally, public attributes on JavaScript classes may be accessed from anywhere in your code. To be able to alter the code that implements the class over time, a library may want to have a stable interface. This runs the danger of exposing certain fields that aren’t intended to be accessible from other parts of the code.

Private fields have previously been identified by starting the class name with an underscore. Nevertheless, no safeguards against access from outside the class have been included by the JavaScript programming language. Private fields, however, can be accessed immediately within the body of the class in which they are declared by prefixing the field name with #.

Temporal

A wide variety of dates, hours, time zones, calendars, and even public holidays are all included in temporal objects, which are global objects. It will provide a simple method to arrange dates, times, or more intricate arrangements, including various time zones.

Error-cause (Chaining error)

A feature called “error cause” enables occurrences of the error to indicate that another error was the root cause of their own. When you desire to capture errors that are thrown within a deeper nested function call, and you want to attach extra information to them, this becomes crucial.

Conclusion

The most sought-after programming language in the IT sector in 2022 will still be JavaScript. It keeps up with user and web developer expectations because of its regular improvements.

Depending on your needs, you may select the ideal JavaScript framework for your website or application. In 2022, JavaScript will be used for mobile and web development to create aesthetically appealing, scalable, reliable, and secure apps for front-end and back-end development, as well as other web development services.

The Best Practices To Build Your Flutter App

November 10, 2022 Comments Off Roxana read

Flutter is an open-source UI software development kit developed by Google. Flutter 3 is the updated version that allows you to build, among other things, apps for iOS and Android. Flutter uses widgets to help you build your UI. Let’s dive into ways that can help you build better apps with Flutter.

Be aware of the concept of constraints in Flutter

The rule for the Flutter layout is: Constraints go down, sizes go up, and the parent sets the position. A constraint has a set of four doubles which are the following: a minimum and maximum height and a minimum and maximum width. A widget derives its constraints from its parent, which then passes them to its children one by one, which then informs the widget of its size.

The constraints can also be different for each child. After the children are positioned by the widget on the x and y-axis. The final step is that the widget passes its size to the parent.

Remember that child widget constraints are always defined by those of its parent and cannot be defined on their own.

Keep Build Functions Pure

Get rid of any operation that may affect the rebuild performance. The reason for this is that certain external factors can trigger a new widget build and cause problems. Some of these factors include parent widgets recreating their child, screen resizing, etc.

Use Operators Smartly

Use the various operators to reduce the number of codes needed. The Spread operator, for example, takes a collection, like a list, and passes it to the encompassing collection. The Cascade operator allows for a sequence of operations to be used on the same object. Null aware and Null safe operators allow the code to either avoid being run or running your code even if a variable has a null value. It comes in handy to check Null values in conditional expressions.

Use streams only when necessary

Streams should be used only when one wants to handle multiple asynchronous events if one wants to avoid poor memory and CPU usage. Use ChangeNotifier instead to provide a reactive UI. Another way to manner to provide a change to your app state is the use of the Flutter Bloc library. Resources are available there to help you build powerful and reactive apps.

Use raw strings

The use of raw strings to escape special characters like the backslash.

Setup automated tests

Set up automated tests for important elements such as widgets and unit tests. Unit tests allow for the testing of a single method, function, or class. Widget tests allow for the testing of a single widget to ensure that the widget’s UI is looking and interacting as it is expected to. Unit and widget tests are both quicker and less expensive than integration tests. Changes can be tested automatically with continuous integration services.

Prefer relative imports to absolute imports

To avoid confusion and simplify things, it is best to import libraries using relative paths to our package lib directory as they are shorter. This also ensures consistency.

Replace Container with SizedBox

SizedBox is a simple built-in widget that has a specific size. As such, it uses fewer parameters than Container. Using SizedBox instead of Container can simplify things in case you need a placeholder. SizedBox being a const constructor allows the compiler to create slightly more efficient code. Also noteworthy is that parameters can be null for the SizedBox.

Use the const keyword as much as possible

The const keyword indicates to the compiler a variable that will never change in the lifecycle of the code. For example, we can create one widget or variable and add the const keyword in front of it. This prevents the creation of multiple copies of the widget in the memory or makes it easier to reference the convenient object. The benefits of using the const keyword add up, especially if the app is large enough. This also leads to an increase in performance and improvement in hot reload functionality.

Use log instead of print for debugging

This will simplify the output and help with debugging. The debugPrint function prints the whole list of log data errors, while some of them might be missing with the print function. This can happen when working on Android. Another more elegant way is to import dart: developer and use the log function. Logging information can make it easier to spot and understand errors.

Follow the style guide for Dart

Ensuring style consistency will improve the quality of the code and facilitate teamwork among developers. Use the available guides to help you with naming Boolean properties and variables for example.

For example, a line should be approximately 80 characters in length. Use dedicated APIs whenever there is a reason, even if general APIs are preferred. Divide the larger functions or widgets into multiple smaller functions or widgets. It is also better to use a widget class in place of the function returning the widget.

Leave comments in the code if it is not obvious. You can also define constants for magic numbers, so other people know their meaning. Another thing is to divide your constants into logical sections by using multiple classes to define them.

Another important thing is to delete code that is not required and not merely comment it out. And finally, use the code linter to ensure the code is readable and error-free.

How Flutter Can Help Your E-Commerce Business Win the Market Competition

November 9, 2022 Comments Off Roxana read

The E-commerce market is a highly competitive place with the number of new e-commerce businesses constantly growing; those already in the space are always looking for new ways to stay at the front of the market and, in doing so, increase their sales. One of the many advantages of using Flutter for e-commerce is the way you are able to quickly and efficiently able to expand your sale channels by simply using one code base. This will not only cut your time but allow you to list products quicker, meaning you can make sales faster.

In this article, we will be exploring the benefits of using Flutter with your e-commerce business.

E-commerce benefits of Flutter

Team Management

By using Flutter for your e-commerce business, you will only need to create one e-commerce app for both mobile platforms using just one code base. You will not need a large team to manage those apps, and as a result, you will only need to communicate with one development team. This can greatly reduce the chance of miscommunication amongst your team as well as create a more simplified environment.

Reduced costs of e-commerce apps

By cutting down the number of developers needed on your team and running your app as a cross-platform app, you can save roughly 40% of the company’s budget as you won’t have to pay for two native apps. This difference in running two native apps as opposed to one cross-platform app can be as much as $15 000 on average.

Tech-based advantages

Dart-based origin

Using a framework that is both flexible and unique opens you up to having several different advantages that can only be found with the Dart framework.

This includes being able to build native coding without using JavaScript, preventing bugs from this compilation process, prompt development cycles, and having the ability to hot reload, which lets you see the changes to your UI as you create it!

Close to native performance

By using the Skia graphics engine, you get an incredibly high-powered performance that allows your app to run at high loading speeds and have perfect graphics or animations of up to 120FPS. The creators of Skia have just introduced a new graphics engine, known as the Impeller, a 3.3 version that now allows your application interface to run even more smoothly!

Security

Due to the Dart framework base, your coding for your application is encrypted so that any attempts to be reversed engineered will be unsuccessful. This form of security is higher than those found in Java, Kotlin, and even React Native.

The Best Local Databases to Develop React Native Apps

November 7, 2022 Comments Off Roxana read

Among the different frameworks for developing apps, React Native is one of the most popular. React Native is preferred both by large organizations and start-ups to develop apps in a cost and time-effective manner.

React Native is a framework of choice for building offline-first applications that can run without internet connectivity.

Database Aspects for React Native App Development

Various aspects are to be considered when choosing a React Native database.

Ease of Use

Use a database that is easier to manage and integrate for your team. That is an obvious point, but one always worth remembering.

Data Complexity

Selecting a database that can handle complex objects is essential since data is maintained in the form of JSON structures or key values.

Management of Memory

Memory handling is important because if the data is not maintained properly, then the apps risk crashing more, although most databases clear their cache at a certain time interval to have sufficient memory.

Synchronization of Offline Date

Being able to synchronize data after a device connects to the internet or the internet connection is restored to full strength is more and more important as users need their apps to be able to work offline.

Data conflicts resolution

Selecting a database with the appropriate conflict management policies and syncing management is a must, as some features may lead to data conflicts.

Concurrency

Understanding the key concept of concurrency is important. As your app gains in popularity, it will have to deal with an increased number of requests and users. Concurrency is hence the ability of a database to allow multiple transactions by multiple users to happen at the same time.

Examples of Local Databases Used in React Native App Development

Firebase

Firebase is a database that supports NoSQL and is owned by Google. It is best suited for apps that require data to be synchronized and updated offline. For MVC React Native apps that require a lot of data, Firebase is the best.

A combination of Firebase with a wide variety of apps can be done simply. It includes tracking tools for performance and bug detection. Other perks include ease of setup and great security, along with the possibility to prototype apps fast.

Realm

An open-source, cross-platform used for mobile applications and websites. Realm is a high-performance database favored for large apps. The database is object-oriented and can support a wide variety of complex data types.

The database has its own search engine, and key-value stores along with object-related mapping are not required. It has a wide range of API sets and is faster than many other databases. Realm can also fix queries better in comparison to SQLite.

SQLite

SQLite is a lightweight relational database management system that was built to offer the user the capacity to store mobile apps locally. Performance might not be as great as other databases. With SQLite, data can be saved in a cross-platform database file, and management is done in a hassle-free manner. SQLite can execute almost all SQL standards.

Watermelon DB

This database is built on SQLite, which makes it very scalable and useful for creating difficult apps that need real-world performance. Using lazy strategies, it manages the persistence of data with slower devices.

Engine synchronization allows it to enable an offline-first system. Changes in the Ui are automatically rendered in the UI. Other characteristics include static typing with the flow and being able to plug data into components.

5. PouchDB

A lightweight open-source Javascript database that conserves data in a JSON format. It runs embedded in the web browser, thus making it extremely fast. Using a JS API allows it to enable all delete, read, update and create functions. In PouchDB, data is stored locally when the application is offline until the connection is restored. At that moment, the data is synchronized with CouchDB and servers.

Replication features facilitate the syncing of data with multiple clients while preventing data loss. Its support of SSL makes it one of the most secure, if not the most secure, for data.

Final Thoughts

The storage system that you use will depend on the type of app that you build and other constraints such as cost, security, scalability, etc. Choosing the most adapted form of storage might be a determining factor in the experience the users have with your app and its success of it!

Is there anyone who hasn’t heard of Netflix by now? Netflix burst into our lives and swiftly surpassed all other subscription services, with over 200 million subscribers in 190 countries receiving their favorite movies and television shows. As a single monolithic program, it had 40-minute startup times and required writing the same lines of code twice, once for the server and once for the client.

The world’s largest streaming service opted for Node.js due to the relative simplicity of the framework, the fact that it avoided the need to write code twice, and its exceptional speed. The team ultimately decided to switch to Node.js from a monolithic JVM-based system due to issues with vertical scalability.

Thus, the Netflix team could convert the site to a single-page application, cutting load times to under a minute. Thanks to Node.js, Netflix’s single-page design is user-friendly and has a lightning-fast load time.

LinkedIn

LinkedIn is an impressive success story as a business-oriented social network with over 830 million users. They joined the Node camp when the framework was just a year old but was gaining momentum quickly.

After switching to Node.js for the app’s backend, they saw significant speed improvements (up to 20 times quicker) and integration (between the app’s front and back ends).

PayPal

Over 400 million people use PayPal, a payment system that began as a Node.js development platform before it switched all its Web applications from Java to Javascript and Node.js.

Using the same language on the server and client sides improved internal communication and overall product knowledge, which was a major element in the decision-making process.

When it comes to online payments, every second counts, which is why PayPal’s developers were able to reduce response time by 35%, which resulted in websites being provided 200 milliseconds quicker while also writing 33% fewer lines of code and using 40% fewer files.

eBay

While the American e-commerce behemoth eBay would seem like it would only be interested in tried-and-true technology, it picked the then-emerging Node.js because of the benefits it promised and the developer team’s willingness to try new things.

Additionally, the major objective was to coordinate many eBay-specific services showing data on the page, e.g., performing I/O-bound tasks, so that the application could remain in “real-time” as much of the time as feasible.

Since Node.js proved so successful on the backend, the team behind the project decided to create a Node. js-based frontend stack that could take advantage of the majority of the code already written.

Uber

This ride-sharing network has expanded rapidly over the past few years, with operations in more than 70 countries across six continents and the processing of millions of rides every day.

Node.js was deployed to create a vast system for matching drivers and riders. This was done because Node.js is well-suited to distributed systems that make many networks queries to swiftly analyze enormous volumes of data.

According to their blog, “xxxNode.js offers us the flexibility to manage enormous volumes of concurrent connections,” making it the ideal choice to power the original core trip execution engine.

One such factor was the huge number of web developers that back Node.js.

Similarly, the business describes an API Gateway, one of the largest NodeJS apps at the time, which communicated with over 2,200 micro-services:

Peaking at 800,000 requests per second
Nearly a million lines of code are concentrated in the area of core user flows.
Among other stunning statistics

Even though they were “one of the first two organizations to deploy Node.js in production,” the company nevertheless takes great pride in being an early adopter of the language.

The Most Notable JavaScript Frameworks for Developing Mobile Apps

November 7, 2022 Comments Off Roxana read

Mobile apps have exploded in popularity in the past few years as mobile devices have taken over our lives. The market size for these apps is estimated to be over 200 billion in revenue in 2022. This means that there is a need to build quality apps whit excellent user experience that can be deployed across multiple platforms. JavaScript for mobile development allows you to reach these goals.

Reasons To Use JavaScript Frameworks for Mobile Apps

As mentioned earlier, JavaScript is suitable for multiple platforms, including Android, iOS, and Windows. JavaScript allows developers with different degrees of proficiency to build highly responsive applications that can be deployed quickly. It is relatively easy to learn, which makes it a popular programming language with a great community to support the developers. The extensive libraries built due to JavaScript’s broad adoption in web development means that pieces of code are easy to find to help you develop your application. The setup to get started is relatively cheap, making it a great choice for small start-ups and organizations to large ones.

Being so extensively used in web development and mobile applications, it is easy to find developers who can use JavaScript frameworks for mobile or transition to those frameworks with relative ease. And again, the point is to build applications with excellent user experience, something that can be done with JavaScript as it makes your applications more dynamic with the support of interactive elements and audio and video elements.

The Most Popular JS Frameworks for Mobile Apps

jQuery for Mobile

jQuery is a lightweight open-source framework that allows you to build applications that load quickly and are compatible with a wide range of screens and resolutions across multiple devices. It is HTLM-5 based and is supported by the most popular web browsers. It requires minimal scripting and also allows the creation of custom themes.

Apache Cordova

Another open-source framework that allows the development of cross-platform mobile apps using JavaScript, CSS, and HTML. Plugins allow access to various components and files of a device, including the GPS, file system, camera, and SIM cards, among other things. The Cordova Command Line Interface allows you to build your projects for different platforms and emulate them.

Mobile Angular UI

Mobile Angular UI is an open-source HTLM5 framework that allows the development of hybrid apps with a near-native-like experience. It is a common code framework that makes it easy to learn and use. The fact that front-end code can be reused between web development and mobile apps is translated into lower development times. This is also seen in the synching of the Model and View layers that allow a user to see changes in the data of the Model layer.

Ionic

Ionic is one of the best cross-platform open-source frameworks for hybrid mobile apps. It uses a single shared codebase of HTML, CSS, and JavaScript. It allows developers to build apps with Angular, React, Vue, or simple Vanilla JavaScript. The significant number of plugins available and using a unique code across multiple platforms allow for faster development times with reduced costs. Over 100 UI components, typography, and base themes are accessible and ready to use in the pre-designed application.

React Native

Used to build native apps on iOS and Android as code is written in JavaScript but rendered to the native platform UI. Reusable code from web to mobile applications and from one platform to another means savings in time and money. React Native modules are often available as npm packages, making them easy to manage and install.

Ember.js

EmberJS is a lightweight and open-source JavasScript framework that allows for the building of large client-side applications. It includes add-ons such as Fastboot, which allows your Ember application to run in Node.js. One can build single-page applications that are highly efficient since they don’t require refreshing the entire page for each action of the user. EmberJS supports data binding that allows the upgrading of one property when the other one changes. Other features of EmberJS include the Ember Inspector to debug applications, routes to manage URLs, and the use of templates for automatic model updating.

Summary

JavaScript is one of the core programming languages used to create web applications. Various open-source frameworks exist to help developers build robust and interesting applications that can be easily deployed across platforms. Choosing a framework, then, is a matter of which types of application is being built and the needs and constraints of the team.
