How JavaScript Has Become The Most Utilitarian Programming Language in 2024

January 23, 2024 563 Views

JavaScript is unarguably one of the most commonly used programming languages among developers. It’s the fundamental language in the web development landscape and is used by every modern web app. It emerged as a revolutionary scripting language, allowing us to add interactivity to our websites and web apps. However, it had its limitations. Fortunately, JavaScript evolved over time – and is still evolving – adding more features and functions, such as asynchronous operations, event handling, etc., for creating high-performance dynamic and interactive apps. And with the introduction of Javascript libraries and JS frameworks like jQuery, React, Angular, and Ext JS JavaScript framework, the popularity of JavaScript has only increased.

While JavaScript was confined to front-end development for a long time, it has evolved into a versatile, utilitarian programming language. Today, JS facilitates the development of diverse types of applications, including both client and server-side applications.

This article will explore the factors and features contributing to JavaScript’s dominance and widespread adoption, making it the most utilitarian programming language.

JavaScript’s Dominance in 2024

JavaScript was the most used programming language in 2023, with 63.61% of developers using it. It currently powers around 98% of all the websites on the web. It is expected to remain the dominant programming language in 2024, with more advanced and helpful features set to be included in ES2024, such as improved Unicode strings, Atomic waitSync, and Top-level await. Moreover, JavaScript’s versatility, cross-platform compatibility, ease of use, extensive ecosystem, and massive developer community will continue to contribute to its widespread adoption.

Rise of JavaScript in Various Domains

JavaScript’s cross-platform capabilities reflect the language’s versatility, allowing developers to create applications that work flawlessly across platforms, devices, and environments.

JavaScript for Front-End Web App Development

JavaScript was initially created as a simple scripting language to convert static HTML pages into interactive ones. However, its capabilities enhanced over time with features like asynchronous operations and event handling, making it the ultimate language for creating modern dynamic web applications with highly interactive user interfaces.

Today, JavaScript capabilities extend beyond web browsers and front-end development.

JavaScript for Server-Side Applications

The introduction of Node.js in 2009 enabled developers to use JavaScript on the server side. Node.js is a cross-platform JavaScript runtime environment that runs on several platforms. These include Linux, Windows, Mac OS, Unix, etc. This means developers can now use the same programming language (JS) for both client-side and server-side scripting, leading to a more efficient development process. Today, many companies use Node.js for its efficiency, speed, scalability, and cross-platform compatibility to build server-side applications.

JavaScript for Mobile Applications

Cross-platform frameworks like React Native and Ionic enable developers to leverage JavaScript to build mobile apps. For instance, React Native allows developers to build native-like cross-platform mobile apps using React and JavaScript. This means JavaScript developers are no longer confined to web app development. They can utilize their existing skills and knowledge to build Android and iOS mobile apps. This cross-platform development saves time and effort as developers don’t need to create separate codebases for Android and iOS.

JavaScript for Desktop Applications

Frameworks like Electron JS further expand JavaScript cross-platform capabilities. Developers can use Electron JS to build desktop applications using HTML, CSS, and JavaScript. The framework supports cross-platform development, allowing developers to create apps that run on Linux, Windows, and macOS.

Frameworks and Libraries

JavaScript has an extensive ecosystem of tools, frameworks and libraries that make the web development process quicker and easier. For example, a JavaScript library provides pre-written and re-useable javascript code functions or blocks for common JS tasks, accelerating the development process.

Ext JS: The Ultimate JS Framework for Enterprise-level App Development

JS frameworks - Sencha Ext JS - The Best JavaScript Framework

Ext JS is one of the leading JS frameworks that empowers web developers to build high-performance enterprise-level web and mobile applications.

These components are highly customizable and fully tested to work seamlessly across browsers and devices. The framework also offers a blazing-fast JS grid and a diverse range of charts and D3 visualizations for building data-intensive apps.

Other key features of the Ext JS framework include:

  • Component-Based Architecture: Ext JS supports a component-based architecture, enabling developers to create modular, reusable components.
  • MVVM Architecture: The framework supports MVVM architecture, allowing you to separate the business logic of your app from its UI. Moreover, it supports two-way data binding.
  • Cross-Browser and Cross-Platform Compatibility: Ext JS is fully optimized to work flawlessly across browsers. It supports all major browsers, including Chrome, Edge, Safari, and Firefox. Moreover, the framework facilitates the creation of responsive UI designs that can adapt to various screen sizes, such as smartphones, laptops, tablets, etc. Hence, Ext JS delivers a consistent user experience across browsers and devices.
  • Powerful Layout System: Ext JS offers a robust layout system, enabling developers to build beautiful and complex user interfaces easily.
  • Sencha Tools: Sencha also offers various other tools that you can use with Ext JS to build and test your apps efficiently. These include a cmd (command line tool), Sencha architect (a drag-and-drop builder), Sencha Test (a testing tool), Themer, and Sencha Stencils ( a UI asset kit for Adobe Illustrator, Balsamiq, and Sketch)
  • Community Edition: While Ext JS is a proprietary framework, it offers a community edition that you can use to try and test the features of the framework.

Other Helpful JavaScript Frameworks, Libraries and Tools

  • React, Angular and Vue (most popular JavaScript frameworks for front-end development)
  • npm (Node Package Manager)
  • jQuery (JavaScript library for DOM manipulation)
