Why JavaScript Has Become Imperative for Web Developers

In this article, we will talk about why JavaScript has become imperative for contemporary web developers. JavaScript is a programming language that enables you to implement complicated features on web pages such as interactive maps, timely content updates, animated 2D or 3D graphics, and more! It is the third layer of current standard web technologies, with the other two being CSS and HTML. Below, we will look at the reasons for the rising popularity of JavaScript amongst web developers.

 1. Application of Client-side Scripts

As mentioned earlier, JavaScript is a high-level programming language that has been designed specially as a client-side scripting language. Lots of developers are using JavaScript as a programming language for creating their websites. Web developers can use this language to encrypt client-side scripts, which can then be integrated with HTML for producing top-quality output. These are highly accountable for a responsive and interactive web page featuring a better user interface. Besides this, these websites do not deal with much server interaction and help minimize server load in turn.

2. Simple Web App Development

On most occasions, developers will face complicated situations. Fortunately, JavaScript will help solve these issues very easily. One can make use of JavaScript libraries for developing shadow DOM boundaries. These help to disintegrate the individual JavaScript library components. Because of shadow DOM, web browsers can produce documents that are encrypted with HTML tags like select, div, and input. Therefore, JavaScript aids programmers in simplifying the composition of their applications, despite being a programming language that must be interpreted.

3. Write Server-side Code

We know that web developers use cross-platform runtime engines such as Node.js to write server-side code in JavaScript. However, these cross-platform engines have been designed as a server-side runtime environment too. JavaScript code is further executed by Node.js effectively via the Google V8 JavaScript engine. Several inbuilt libraries are held by it, enabling the web developers to execute their web applications seamlessly without depending on any external web server. As a result, the developers are aided by JavaScript in writing client-side and server-side codes by making use of Node.js.

4. Responsive Web Design

It is quite difficult to attract prospective users if the website isn’t attractive and responsive. These are the basic elements of a website; utilizing the business logo to establish a strong impression of the brand and survive in this market where there is lots of competition is integral. For this reason, the majority of developers aim for a responsive web design. It is only possible to create such websites with the help of JavaScript. As mentioned before, JavaScript is blended with HTML5 and CSS3 on most occasions. These allow web developers to make a flawless website for mobile gadgets as well as computers. Therefore, developers must make use of JavaScript for creating these types of web pages. 

5. Usage of MEAN Stack

The developers can further simplify the development process by leveraging the MEAN stack’s four components, namely Express.js, MongoDB, Node.js, and Angular.js. MongoDB is a NoSQL database that has been newly defined, Angular.js is a popular JavaScript framework that is supported by Google, Express.js is a framework that consists of specific features for simplifying any website’s development with only one page or multiple pages, and Node.js is a cross-platform which has been designed as a popular server-side runtime environment. These four components of the MEAN stack enable experts to write the back-end and front-end of any website in JavaScript.

6. Usage of Transcompilers

Every single stack consists of a couple of ends. Also, JavaScript fails to provide some essential features which can be obtained easily from other programming languages such as C# and Java. However, that is not the end of the story. It is feasible for a professional web developer to extend the JavaScript features quite easily. They can do this with the help of transpilers or transcompilers such as CoffeeScript, DukeScript, TypeScript, and Vaadin. Every single transpiler helps to fulfill the specifications of large apps. Even though this process might appear to be useful, it makes the workflow complicated as well.

7. Google AMP Project

AMP stands for Accelerated Mobile Pages. Google has introduced the AMP project for developing websites that can be run on different mobile gadgets. Several optimization techniques have been integrated for amplifying the loading speed of mobile web pages. However, this project cannot deliver the exact output until AMP technology has been integrated with JavaScript, HTML5, and CSS3. The role played by web developers comes to use right now. Thus, it is evident that the experts’ primary ingredient in bringing out the featured output is going to be JavaScript. 

8. Usage of Frameworks and Libraries

The developers can use the frameworks and libraries of JavaScript for extending its usage. These featured JavaScript libraries consist of React.js, Ember, and Angular.js. In this way, the JavaScript developers can incorporate functionality to complicated web applications without writing any additional code. You will also come across open source tools such as NPM, which can be employed to install and manage the JavaScript libraries. 

Conclusion

I hope that this information will help you comprehend why JavaScript is imperative for web developers.
