5 Reasons Why JavaScript is Still the Programming Language of the Future

There’s no denying that JavaScript is one of the most popular technologies in the tech industry today owing to its performance and omnipresence. While companies have traditionally hired JavaScript developers for frontend development, new tools and frameworks such as Node.js allowed expanding JavaScript to the backend as well. 

We are currently in the middle of a major transition in the programming world, where JavaScript is becoming the language of choice for all types of programming. The sheer number and variety of applications you can build with it show the potential of JavaScript in powering future trends such as mobile applications, wearable technologies, and the Internet of Things. 

A number of reasons attribute to JavaScript being the programming language of the future:

1. The Introduction of Node.JS

Node.JS has been a game changing tool of the programming world. Node.JS is the most popular framework in the U.S with more than 28,000 websites relying on it.It powers the backend of the big online marketplaces including AliExpress, eBay, and more. Node.JS is used by websites that get a heavy traffic, such as Netflix, PayPal, and Groupon.

Node.js essentially allows JavaScript to do just about anything any other programming language can do. Traditionally, front-end code was written with HTML, CSS, and JavaScript, and backend code had to be written in C, Python, or Java. Node.JS now allows you to write backend code in JavaScript. This means that a self-taught developer now only needs to learn JavaScript in order to write frontend and backend code.

With the birth of Node.JS, came the Node Package Manager (also known as NPM), which made the JavaScript language completely open source. This completely transformed the way JavaScript development services were used by JavaScript development companies.

2. React.JS to Level Up Performance

React app development services have been deemed the most sought-after services by businesses around the world that value creating their online image through a reliable, functional, and aesthetically appealing app or website for their company. With the biggest organizations and Fortune 500 companies in the world, namely Facebook, Twitter, Instagram, Tesla, etc. turning to React JS development companies to build their apps, the demand for hiring React JS developers has grown at record pace. React.js offers a great level of flexibility and performance that can help businesses build a scalable solution complete with interactive UIs.

React.JS utilizes a powerful algorithm known as Virtual DOM that can be used to compare the current page structure with the planned page structure and update the right components as soon as any change in the data occurs. It is highly stable and scalable.It uses a single language for server-side, client-side, and mobile applications and is backward compatible. This feature makes it extremely easy for the legacy projects to be upgraded to the latest version of React.js without making any change in the codebase or by making only a few minor tweaks. It is a flexible, component-based and SEO-friendly facility that prompts businesses to hire JavaScript programmers.

3. 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. JavaScript is easy to learn and since any programmer needs to learn only JavaScript to be able to manage everything – from front-end to back-end – it makes an excellent option to just learn this one language.

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.

4. Simplify Complex Web Application Development

JavaScript is an interpreted programming language, and 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. Developers can write the JavaScript code easily without using any particular program or tool. Various editors are available that developers can use to spot and avoid any mistakes in their JavaScript code. The editor reformats the JavaScript code and allows a developer to discover the bugs and errors in the program quickly and easily.

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 CSS3, HTML5, and JavaScript to make the web pages responsive. The developers can use JavaScript to optimize web pages for mobile devices.

JavaScript has remained the most popular programming language in the world among developers working on varied projects for decades now. Being a robust programming language that assists developers in building large scale web applications easily and quickly, it has earned a reputation among the programmers. 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. JavaScript is well-equipped to take every new technology that is in the pipeline or in the nascent stage. 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.
