Why Millions of Developers Still Trust JavaScript for Web Application Development

Reasons that make JavaScript the most popular programming language by far

Released 20 years ago, JavaScript is still the most relevant and widely used programming language. In fact, statistics claim that around 94 per cent of the websites worldwide are created using JavaScript. 

What is JavaScript? What Makes It So Popular?

JavaScript is a client-side programming language, which helps web developers create robust web applications as well as code for dynamic and interactive web pages by implementing custom client-side scripts. The hired JavaScript developers can also make use of cross-platform runtime engines like Node.JS in order to write server-side code in JavaScript. JavaScript development companies can even create web pages that work well across various browsers, platforms, and devices by combining JavaScript, HTML5, and CSS3.

There are a number of JavaScript Frameworks available in the web market today. Some of the most popular ones include Angular.JS, React.JS, Node.JS, etc. By using these frameworks, a remote JavaScript developer can reduce the amount of time and efforts required for developing JS-based sites and apps. 

JavaScript allows the programmers to build large-scale web applications easily as it plays an important role in simplifying the whole process of developing large-scale web applications.

Over the years, JavaScript developers have made several improvements to the language. Enterprising JavaScript programmers have created libraries – more concise languages constructed from the building blocks of JavaScript that are less complex and can be targeted for specific applications. For instance, JQuery is a JavaScript library that simplifies and expands many JavaScript animation and interactive functions, while Backbone.js makes responsive design easier.


JavaScript has become integral to the Internet experience as developers envisage to increase the interaction and complexity in the applications built. Search engines, e-commerce, content management systems, responsive design, social media, and phone apps would not be possible without it.

Benefits of Using JavaScript for Application Development

JavaScript is a great option for developers planning to build a diverse set of applications. The following advantages are offered by JavaScript that ensure that it still remains the most popular web application development language.

What makes JavaScript so popular for web app development?

1. JavaScript is Cross Browser Compatible

One of the best things about JavaScript is that it is supported by multiple web browsers, which include Google Chrome, Internet Explorer, Firefox, Safari, Opera, and more. Therefore, it makes it possible for the users to access the web applications on any web browser of their choice easily. They simply need to enable the JavaScript language if it has been disabled, and can enjoy all the functionalities present in the site or web app.

2. JavaScript Includes a Number of Libraries and Frameworks

JavaScript Frameworks and libraries make it easy for web developers to build large, JavaScript-based web applications. There are many dynamic JavaScript frameworks such as Angular.JS, React.JS, etc. By making use of these frameworks, developers can easily, quickly, and efficiently develop highly interactive and professional web applications. JavaScript also hosts a number of libraries that can be used by developers as per the requirements of a project and for accomplishing specific tasks.

3. Easy to Write JavaScript Code Without Using Any Specific Tool

Developers can write the JavaScript code easily without using any particular program or tool. All they need is a notebook and they can start writing. Various editors are available that developers can use to find out any mistakes in the JavaScript code. The editor reformats the JavaScript code and allows a developer to discover the bugs and errors in the program quickly and easily.

4. Simplify Complex Web Application Development

JavaScript is an interpreted programming language, yet it simplifies the development of complex web applications by allowing the developers to simplify the application’s composition. The developers can use JavaScript libraries to create DOM boundaries. This shadow DOM further makes web browsers deliver documents with widely used HTML tags like select, div and input.

5. Responsive Web Design

Responsive web designing is the latest requirement of businesses to make their web applications incorporate accessibility and an ability to work well across multiple browsers and devices like smartphones and desktops. Responsive web design enables the developers to optimize the site for both stationary and mobile devices using the same code. The developers have to combine the CSS3, HTML5, and JavaScript to make the web pages responsive. The developers can use JavaScript to optimize web pages for mobile devices.

6. Google AMP Project

Google has started the Accelerated Mobile Pages (AMP) project to create websites which deliver richer user experience across various mobile devices. Google has implemented many optimization techniques to increase the loading speed of the mobile web pages and it requires developers to integrate AMP technology into the web pages by using HTML5, CSS3, and JavaScript. This implies that any developer will have to use JavaScript in order to optimize websites for mobile devices for AMP.

As observed from the points discussed above, there are several reasons why JavaScript has remained the most popular programming language in the world among developers working on varied projects. JavaScript is a robust programming language that helps developers in building large scale web applications easily and quickly. It not only helps build highly interactive web apps, but also helps in enhancing the speed, performance, functionality, usability, and features of the application without any hassle.

Now developers and programmers are increasingly using JavaScript to make their web applications deliver the best and the most optimal user experience across various devices, browsers, and operating systems. It is essential for developers to learn about various JavaScript libraries, frameworks, and tools and combine multiple libraries and frameworks to deliver as per the unique requirements of any project.
