Why JavaScript is Important for Web Developers?

Given that JavaScript powers nearly 94.5% of all the websites online, one can understand the importance of this web technology. JavaScript allows developers and programmers to create web pages that are dynamic and interactive. Interestingly, JavaScript ushered in the age of animated websites with adaptive content. It even introduced form validation. While JavaScript may be combined with HTML5 or CSS3 for web page creation, it is still one of the foundational programming languages.

Following are some reasons why JavaScript remains to be relevant even in these modern times:

JavaScript Helps Implement Client-Side Scripts

A popular client-side script, JavaScript performs all tasks on the client’s machine without interacting with the server. Thus, even if your internet service provider is experiencing downtime and the website  is already loaded on the client’s device, you can still interact with it on the browser. However, you will be unable to navigate to any other web page.

Furthermore, JavaScript codes can be seamlessly integrated into with HTML for a rich user experience.

You Can Write Server-Side Code Using JavaScript

In addition to writing Client-Side Scripts, you can also use JavaScript to write codes at the server end. However, in this case, you need to make use of a cross-platform runtime engine such as Node.js. Through Node.js, you can run codes on the Google V8 JavaScript engine. Additionally, the inbuilt library available in Node.js allows programmers to execute their applications without the dependence on external web servers.

Hence, JavaScript training can prepare you for running an application right from the back-end to the front-end.

JavaScript and MEAN Stack

Using JavaScript, you can simplify the composition of the web application and execute it through the MEAN Stack. There are four components of MEAN Stack, namely:

  • MongoDB – a modern, schemaless NoSQL database for data storage
  • Express.js – a feature to simplify the development of single-page and multi-page website
  • Angular.js – a popular JavaScript framework that is supported by Google, and
  • Node.js – a server-side and cross-platform runtime environment

Using the MEAN stack, you can develop a uniform program in the JavaScript environment from the server-side to the client-side.

However, it must be mentioned here that the various components of MEAN Stack are interoperable.

JavaScript Helps Create a Responsive Web Design

Currently, websites are putting everything out there to lure in their audience. This has led to a cut-throat race to offer a seamless and rich user experience. Further, websites have to be accessible across various browsers and should look pleasing even on different devices.

Thus, webmasters are looking for responsive web designs that will look good on mobile phones and laptops, while being written on a single code base. JavaScript can be used to optimize the web pages to make them compatible and responsive even on mobile devices. The Google AMP Project also looks for websites that make use of HTML5, CSS3, and JavaScript to optimize the webpages through AMP.

JavaScript has a Vast Library and Useful Frameworks

Web developers find it easy to extend the functionality of their JavaScript code with the help of supporting libraries and frameworks. JavaScript libraries such as AngularJS and Ember are loaded with features and they can easily be added to complex web applications without the need for modifying the code or adding to it.

On the other hand, there are also lightweight JavaScript libraries such as React.js, which make it easier for web developers to achieve specific goals. Further, open-source tools such as NPM can be easily used to efficiently manage all the active JavaScript libraries that are being used by the web application.

It Has the Potential for Future Development

JavaScript lacks a few advanced technological features that are offered by modern-day programming languages. However, that does not mean that there is no scope for introducing such features in JavaScript. In fact, JavaScript has been evolving and releasing versions that get it at par with the modern programming languages.

JavaScript was the first and continues to be the only client-side scripting language that can be used as a procedural and an object-oriented language. A number of web developers are making use of JavaScript to build rich, engaging, user-friendly, and viewer-centric websites that will positively benefit an average internet user’s experience.

Considering JavaScript is universally used online, it brings about consistency across the entire internet culture. Professionals who have undergone a JavaScript course are well-versed with the foundational knowledge of the programming language. As such, they are better equipped to develop web-based applications that can be viewed uniformly regardless of where it was designed and where it is being used.
