Swift Vs. Objective-C: Which One Is Better?

February 25, 2021 Comments Off Roxana read

Swift is a programming language created by Apple and one of the most rapidly growing languages currently. It is an alternative to Objective-C – the well-known programming language for iOS development.

Swift has several advantages, some of them including being open-source and backed by a large community, as well as being safer, faster, and easier to read and write. With better memory management and support for dynamic libraries, it is easy to see why Swift has been becoming so popular and taking the leading position when compared to Objective-C.

Read on to find out more about which programming language is better for iOS development – Swift or Objective-C.

Swift offers a higher speed

Swift is offering the high speed of performance modern technologies need. It shows the same performance as C++ for the Mandelbrot and FFT algorithms. And since Swift is a relatively young language, it is expected that more enhancements will be available soon. With its rapid development, no doubt Swift is the language of the future, while Objective-C is only showing worse results.

Swift focuses on safety

Swift was created with a huge focus on safety – it will produce a compiler error each time you write a piece of bad code. This is a huge advantage because it means that bugs can be fixed early in the development stage and you will not have to review the entire code afterward. Less working time for the developers and better experience for customers is definitely a huge advantage to Swift when compared to Objective-C.

Swift is much easier to read and write

The simple syntax of Swift is one of the main reasons why it is becoming so popular. This makes it so easier to read and write code. And since it requires fewer code strings to implement any option, it helps to avoid additional mistakes and keeps the code cleaner, which is not the case with Objective-C. Swift is also easier to understand for coders who use JavaScript, Java, Python, C++, and C#, so they can effortlessly adapt code written in Swift to the existing toolchains.

Swift provides better memory management

Because Objective-C uses Automatic Reference Counting, supported by object-oriented code and the Cocoa API, it can lead to large leaks of memory. This problem is resolved by Swift which uses procedural and object-oriented code paths so that developers can focus on the features and logic of the application instead of having to manage the memory within.

Swift has support for dynamic libraries

Swift uses dynamic libraries which means that you can update your applications as soon as there is a new version of the programing language. Dynamic libraries connect pieces of code directly to the application which helps to reduce the initial size of the app, speed up the loading of external libraries, keep it up to date, and minimize the time for loading new content.

Swift is open-sourced

Being open-sourced and supported by a large community means that you can use the programming language for free and rely on other users to find any issues or problems you might face. The community is also very active in bringing enhancements to Swift and work on its further development.

What is JavaScript Used For?

February 18, 2021 Comments Off Roxana read

JavaScript is the most popular programming language in the world and according to a survey conducted by Stack Overflow in 2020, more than 63% of developers are using it.

It is easy to start with and there are lots of frameworks and libraries that are built with JavaScript. Even though at the beginning JavaScript was only possible to run on web browsers, today it can be run both locally and on a server. This means that it can be used for the development of complete applications – both front- and back end.

Read on to find out what you can use JavaScript for.

Front-end web development

Front-end development, also known as client-side development, is concerned with that part of the web page that users see and interact with.

JavaScript is one of the three main technologies for front-end development – the other two being HTML and CSS. While HTML is all about the structure and content, and CSS is about styling, JavaScript is what makes the page dynamic. This can be achieved in several ways:

Presentation – create sliders and carousels using JavaScript libraries such as Swiper JS, Reveal JS, and Owl JS to customize the presentation of the website.
Animation – using animations is a great way to make the website more attractive. Choose a library like Anime JS, Mo JS, Greensock JS, and Animate on Scroll – all these are built for JavaScript and aim to make the creation of animations easier.
Single page application – you can build a SPA with JavaScript frameworks and libraries like React JS, Vue JS, Polymer JS, and Angular JS.

Back-end Web Development

Back-end development, or server-side development, is about the part of the web page that has to do with APIs, databases, cloud services, file servers – or everything a user does not visually interact with.

Using JavaScript for back-end development is possible thanks to runtime engine Node.js. There are different frameworks that can be used to simplify the back-end development process, such as Express JS, Fastify, and Koa.

Game Development

Games are also possible for development with JavaScript and depending on the complexity of the game, there are different ways to use JavaScript.

You can use JavaScript, HTML, and CSS to build simple 2D games, and for more complex game designs, you can use a JavaScript game engine such as Babylon JS, Phaser JS, and Lime JS which will help you make the process easier.

Mobile App Development

JavaScript can be also used for mobile app development and you can benefit from various frameworks and libraries. Some of these include:

React Native: an open-source framework for building cross-platform native apps.
NativeScript: one of the most popular cross-platform frameworks that can be used for the development of native mobile apps for iOS and Android platforms.
Ionic: another popular JavaScript framework that can be used for the development of hybrid apps.

As you can see, JavaScript is a multipurpose language that can be used for many different areas of technology. And due to its popularity, you can rely on a large and active community to reach out to in case of any issues or questions you might have.

Blockchain is one of the hottest trends of the decade. It was quite hard to develop, but thanks to Python being a very readable language, the process is so much easier. Through Flask, a Python framework, HTTP can be used to request communications with their blockchain over the internet and build endpoints for many blockchain features. Engineers can also execute scripts to develop a decentralized network.

6. Data Science and Data Visualization

Python has various libraries, such as Pandas and Numpy, that simplify the process of extracting data. Other Python libraries such as Matplotlib and Seaborn, are great tools for data analysis. Keep in mind you can use these libraries to plot graphs and display data. Most businesses tend to build smartphone apps for advanced services in data analysis and science.

7. Web Scraping Applications

Spiderbots, otherwise known as Web Crawlers, are used to replicate a list of all the sites viewed on the internet for later processing by a search engine. The collected resources are then indexed to renders for convenient search which makes them useful for automatic maintenance activities on the Web. Python is perfectly suited for this task because it is quick and has, as mentioned earlier, excellent libraries.

8. Business Applications

Python is used in building ERP and eCommerce software solutions because it promotes functional mobility. Odoo, for example, is written in Python. Odoo has a wide variety of enterprise applications that are used as tools in enterprise management. Tryton is an example of another very useful business software that is written in Python.

9. Audio and Video Applications

Python is also used to explore all the video and audio content on the internet. Some of its libraries include PyDub and OpenCV, both of which are helping to complete the development of software effectively. The world’s most popular and powerful audio/visual app YouTube was built using Python. So, yes, that’s how great Python is!

10. System Administration Applications

System maintenance can be a long and cumbersome task with a ton of data to be handled and thousands of activities that need to be completed. Python also saves the day when it comes to devise administration software. It allows developers to connect with the operating devices using the “os” it currently operates on.

As you have seen, using Python as a programming language comes with so many benefits. Regardless of the type of app you want to build, Python can definitely help you.

It is scalable, user-friendly, efficient syntax, and compatible. Python also has so many toolkits, plugins, and libraries. What else can you ask for?

Java versus Python: The Battle for Language Supremacy

February 2, 2021 Comments Off Roxana read

When it comes to choosing a programming language to help develop your applications, you might find yourself stuck between choosing which is the right one for you and the application you wish to build. There are hundreds for you to choose from and a lot of those are battling for the top spot when it comes to business superiority.

We are going to look at the difference between Python and Java. We all know that programming languages are the building blocks for all modern software development. These applications are held together by frameworks as well as APIs. Knowing the difference between the building blocks can benefit you and help you build the perfect application.

What are Java and Python?

Java and Python are the most popular object-oriented languages in the world at the moment.

Java is undoubtedly the fastest and most reliable programming language a developer can use. It is owned by Oracle and was designed to look and feel like C++ however, it is more simple to use when you are developing your application.

Java offers you the opportunity to create everything from desktop software to mobile applications for Android. There is no doubt that this is one of the main reasons as to why this is a top choice for many businesses that are looking to break into the web and mobile application sectors.

Taking a look now at Python, is it one of the most accessible languages in the world at the moment. It allows developers to have limited technical experience of the rhetoric and allows them to edit and create an application. This shows how easy it is to learn this language.

Python has dynamic typing and binding options that allow developers to focus on the readability of the code itself. This makes the language a more cost-effective as well as quicker alternative for your business.

What do Python and Java share?

Java and Python are both object-oriented
Java and Python have a large community backing
Java and Python both take out the trash

What is the difference between Java and Python?

They both have different language structures. They use different techniques to create software. If you want to develop an application with both languages, the odds are that you might need to hire multiple developers.

Java developer will enclose an instruction in a bracket, whereas a Python developer will utilize an indentation to perform the same tasks in a text editor.

When it comes to the speed of these languages, Python runs slower than Java when compiled, it may take less time to write in a text editor. With that being said, if you require a language with a faster runtime, then you need to look at using Java over Python.

Java is better equipped for mobile development which means if you want to write an application that will be used for mobile application, then Java is going to be your best bet.

Python is a better language for less-experienced coders. This means that if you are a start-up business or are busy teaching your new employees, you might want them to use Python before they move onto a different language such as Java.

Java Development Methodologies for Your Business

January 28, 2021 Comments Off Roxana read

Creating a Java software piece to develop an application is a challenge that will always require a highly skilled development team provided with the right tools. One of the most critical aspects of the process is identifying which Java development methodology will be best suited to the project. So how to make the right decision? To help you, we have put together a list of the methodologies to consider. In our previous article, we have discussed four of these methodologies. Let’s check out five more.

Other Java development methodologies

The big bang developer model

Businesses will know that clients aren’t always are of all their requirements when starting a project or don’t have a defined idea of how the finished product will look. Favored for smaller projects, the Big Bang model doesn’t follow a formal procedure involving little planning in deploying and creating an application. This makes it easy to manage and straightforward, therefore interesting for new developers to hone their skills before taking on larger projects.

Its primary downside is that it struggles to take on complex or large-scale projects; similarly, if something doesn’t meet the client’s demands, you may have to restart the entire thing from scratch.

Rapid Application Development (RAD)

RAD is a more precise methodology than others, leading to higher-quality results and a quicker development process. It reduces potential risks by encouraging end-user participation during development, producing quick and continuous code reviews to ensure there are no disappointments at the finish line. If this is the method you choose, you’ll need to create a highly skilled team of developers who have both business knowledge and top-class Java expertise to identify the end user’s exact requirements. You’ll also need to keep in mind its high-cost margins for modeling and automated code generation.

Extreme Programming

XP is another agile methodology, mostly used for production in volatile environments due to its high flexibility level. It focuses on customer involvement, forcing the end-user to identify and stick to a development, testing, and deployment schedule. This leads to lowered software building costs for the end-user and means that XP is only as effective as the developers working on the project.

While it can produce high-quality software with a limited amount of effort, XP still struggles with handling high amounts of development change. It can quickly overrun the developers with extra work, resulting in delays.

Prototype Model

By encouraging your team to produce a prototype of the application before the major coding phase, the Prototype Model ensures good communication of needs and expectations throughout your team. The time commitment may seem counterproductive, yet allowing the end-user to preview and tweak the final product first can lead to faster production and deployment down the line.

Spiral Model

The saying “better safe than sorry” rings particularly true when it comes to deploying an application. The Spiral Model understands that and prioritizes testing above all other phases. It makes it a good compromise for businesses that need to also operate with high-risk factors, allowing the development team to regularly identify risks and eradicate them before they’ve had a chance to take hold.

Although the spiral model’s negative attributes can outweigh its positives due to the cost of implementing the Spiral Model successfully, for example. Purchasing the tools that will help you identify potential risks may very well add financial strain on your business that a quick development process won’t be able to make up for.

Conclusion

As always, when speaking of development, there are many routes available to you: however, the best-suited one might very well be a personalized mix of them all. It’s good to know that many businesses favor the agile methodology because it allows for both speed and flexibility. But don’t let this keep you from identifying your exact needs, and remember that the most important is to have a structure, whichever that may be.

React or Angular: Which One Should You Choose?

January 26, 2021 Comments Off Roxana read

React and Angular are two of the most popular technologies when it comes to front-end development. They provide refactoring, reusable components, and modularization that can facilitate the work of developers.

React is a front-end library created by Facebook, while Angular is an MVC framework by Google. Both can be implemented for diverse tasks and have contrasting functions. They also have different benefits so it is important to know what are the differences before you choose which one to use. Read on to find out the main reasons why you should choose React or Angular.

Consider the task and requirements

The first step is to determine which technology will be more efficient for your specific project. If you have a limited budget and are focused on the speed of development – React is the better choice. It uses virtual DOM and evaluates its parts so that it can compare previous and existing versions and update if anything is out of order.

While Angular is better suited for multifunctional projects as it applies DOM which updates all fragments until it finds the necessary tag. This might affect the performance of the app. There are updates released every six months which means that developers will need to make adjustments.

Overall, React is lightweight and more superior, and better if you plan the update the application over time. Angular provides more tools and is more complex thus being suitable for more heavyweight apps.

TypeScript or JavaScript programming languages

React uses JavaScript which has dynamic typing which means it requires less time for writing code and provides developers with more flexibility. Angular uses TypeScript which has static typing and has more complicated syntax so it requires some previous experience. On the contrary, React requires less learning.

And while JavaScript is more popular with users and has more perspectives, TypeScript is still improving and attracting new customers.

Pros and cons of Angular and React

Both technologies have strengths and weaknesses and different companies have different preferences thus choosing one or the other. For example, React is implemented by WhatsApp, Netflix, and the New York Times, while Angular is used by Apple, Grammarly, Xiaomi, and Nike.

Some of the main advantages of React include the effective use of virtual DOM, great flexibility, lightweight databases, easier browsing for search bots, simple migration between versions, improved user interaction. Some of the flaws are its confusing syntax and chaotic documentation.

As for Angular, its main benefits are the vast number of tools, interrelated functions, and minimal risk of making mistakes, detailed documentation, and architecture made for scalable applications. Its main cons include relatively slow performance and the fact that it is more difficult to master.

In conclusion, both are stellar choices depending on your needs and preferences. If you are developing a real-time app, for example for chatting, choose Angular – a stable and reliable technology. But for single-page and cross-platform apps choose to use React to utilize more flexibility and support from the community.

Best Java Development Methodologies

January 21, 2021 Comments Off Roxana read

What is a software development methodology?

In simple terms, a methodology can offer your team different features and practical ideas to help the production of an application. Each one comes with a specific package of methods that will help you meet deadlines and create quality products, by creating a plan and structure for each task on the way to the finish line. They can usually be divided into two main categories (Agile and Waterfall), although some of them incorporate elements of each. You will need to weigh in the pros and cons of each to decide which one will be the best fit for you.

Waterfall development methodologies

One of the more traditional methodologies, Waterfall development is considered a ‘classic’. It offers teams a sequential development cycle to follow, which ensures every task is fully completed, allowing software production to flow downwards (like a waterfall). It is linear and rigid, ensuring that each phase is completed and tested before moving on to the next step, which makes it a common choice for businesses.

Its main advantages are that rigorous consistent testing saves time long-term and create a stable environment with clear-cut objectives. It’s also useful for smaller projects with limited resources, as Waterfall can help to break down tasks and allow everyone to be involved in the development process.

While it’s effective for quick turnover, its downside is that there is no way to produce a working application until you’ve reached the final stages of development, and you won’t be able to check if the build has been successful half-way through, which may delay fixing bugs. You’ll also need to know all the requirements for your project upfront since there won’t be room for maneuver down the line or changes past the testing stage.

Iterative development methodology

If you’re interested in the waterfall model but want something simpler to upkeep, the iterative development methodology could work wonders for you, by breaking down your project into smaller and more manageable chunks* and testing the code in repetitive cycles to catch bugs earlier. This way, each phase of development is gated and will need design approval before starting coding, which may slow down the overall process but will surely offer you more flexibility.

It also offers additional features that can be incorporated into the software which will enhance the final product’s quality.

Agile development methodologies

In recent years, Agile has become a lot more popular, even overtaking the more traditional waterfall method. Its strict software management process allows for code modifications while an application is being created and deployed, favoring individuals over processes. It allows you to incorporate changes requested by clients while still minimizing the risk of exponential errors by working within cycles of short periods.

You will need constant communication between the team of developers tasked and the end-user to successfully use this method. Only a stream of contact will permit developers to respond to changes when they’re needed, rather than stick to a pre-determined plan.

Scrum methodology

Agile development comes in many different forms, including Scrum, one of the favored ones currently. It breaks down coding and testing phases, into biweekly or monthly iterations (which are called sprints), and production progress is tracked through regular meetings. The unpredictability of Agile can therefore be erased by assigning everyone roles and responsibilities in the process which will never change and encourage continuous delivery. There are three roles, within this methodology, that team members will need to be familiar with:

Product owner: This member is the one with an overview of the entire product, and a vision of how it should come out looking, making it their responsibility to guide developers down the right path and answer whatever questions they may have.
Scrum Master: This is the facilitator between the product owner and the development team, working to remove any obstacles that developers may face and facilitate communication between all members. They deliver new features and then report back any necessary changes or new directives back to the team.
Development team: If everyone does their job properly, the team working on the piece of software should be self-sufficient. It can be a mix of programmers, QAs, tester, and software engineers who organize their own tasks and work together to meet the sprint deadlines.

Kanban Methodology

Kanban is another popular development method, for its agility and flexibility. It offers less structure and is centered around the need to add amendments to code through small incremental changes, meaning you can incorporate it at any stage of development. It’s a non-disruptive method that focuses on not making radical or instant changes to your setup.

A Kanban board will let developers list their current workload organize their work within different lists, ticking off tasks as they go. This method focuses on continuous improvement, with a visual framework allowing you to tackle small changes simultaneously for easier project management. Because, unlike other agile methodologies, it doesn’t offer predefined roles, developers can focus on continuous delivery and balance the demand of tasks if there are numerous changes to be made at once.

One of its drawbacks is that any variability or unpredictability can affect its function, so you’ll need a strong hand managing a spearheading the project in the right direction.
