Why Is JavaScript So Popular?

We live in a world full of modern tools and technologies – and the demand for these technologies is increasing rapidly. Today, every business needs a website or an application to promote their business. These technologies help businesses in brand marketing and build an online reputation.

With the availability of tons of programming languages out there, developers always look for an easy-to-learn language that meets the demanding needs of businesses and users. This is where JavaScript comes into play.

JavaScript is popular - and it is one of the top favorite programming languages by developers and industry leaders. One can use it everywhere: on the web, mobile, server, and even on IoT. According to W3Techs, JavaScript is used as a client-side programming language by 97.5% of all websites. It is also expected that the usage of JavaScript will increase in the coming years.

As compared to other scripting languages, one can’t deny the versatility of JavaScript. Additionally, it stands to be the perfect language for app development.

Why Do Developers Love JavaScript?

JavaScript is popular among developers and industry leaders as it is a server-side language, and it enabled the required scalability in frontend and backend development. It can also be integrated with other languages and can communicate with databases. JavaScript is said to be a more server-side language as browsers have engines that could quickly process it.

Node.js is the prominent JavaScript version, and the demand for Node developers is at its peak. Big companies, including eBay, NASA, etc., have embraced Node.js.

The technical aspects of Java involved in Android app development include Java Standard Edition, Java Enterprise Edition, JavaServer Pages, and more. JavaScript and Node.js developers focus on building a safe and engaging web application for the users.

Easy To Setup

JavaScript is easy to set up language, making it different from other scripting languages. With JavaScript, anyone with a web browser can access the development environment, and every browser supports JavaScript.

Developers can simply run JavaScript on any browser such as Chrome or Mozilla Firefox, and navigate to Developer Tools, and start coding right away.

You can also use a code editor like Visual Studio Code to create a file with the file extension .js to write JavaScript. Visual Studio Code (VS Code) is widely used to write code, but there are other editors which developers prefer.

Community Support

As per the data by StackOverflow, JavaScript has the largest community compared to other programming languages such as PHP, Java, Ruby, Python, etc. Additionally, Node.js has billions of downloads worldwide, making it the most widely used technology.

End-To-End Programming With Node.JS

Node.js allows developers to leverage the power of JavaScript to write server-side code. JavaScript’s popularity is on the rise as Node.js represents the idea of the “JavaScript everywhere” model, consolidating all of web application development around a single programming language, rather than having a different language for server-side and client-side texts.

In short, developers now can use a single platform to manage databases, make HTTP requests, create dynamic content, and provide users an effective user interface (UI). Today, most big tech companies rely on JavaScript, as it is the top-notch language to provide an excellent user experience.


Comparing JS with other programming languages, JavaScript is fast as it runs the right way within the client's browser. When JavaScript uses third-party resources, it slows down the development process.

Major browsers support its JIT or just in time compilation, meaning there would be no need for code compilation before you run it.


JavaScript is an easy-to-use language, and Java inspires it. Also, JavaScript is easier to learn and implement than other programming languages such as C, C++, Python, etc.

Where Is JavaScript Used?

Undoubtedly, the main use of JavaScript will still be frontend web development, but it can do so much more than that.

JavaScript is used in:

Server-Side Code

Developers experienced that JavaScript isn’t made for server-side code, but it became a reliable backend language after introducing Node.js.

Today, this JS runtime is an essential tool to support web servers. Now, JS developers can leverage Node.js to write both frontend and backend scripts in JavaScript without depending on third-party web servers.

Mobile Apps

JavaScript is an ideal programming language to develop Android apps. In the past, developers used Java to create Android apps, but today, it’s easier than ever to use JavaScript to connect to mobile APIs.

The use of JavaScript in creating Android apps opened new opportunities to make them even more exciting for users. For instance, by combining the best of the web and the best of apps, PWAs improve authenticity, performance, and engagement. They also enable new functionalities such as offline navigation.

API Integrations

JavaScript is reliable. Developers can use it to retrieve data from other sources and display it on their site. One idea that is more promoted than ever in web development is modularity – using diverse tools to perform specific tasks. As a result, it’s now easy to build these kinds of the stack – thanks to APIs and JavaScript.

Summing Up

So, is JavaScript dead in 2021?

JavaScript is here to stay, and the demand for JavaScript will increase in the coming years. Today, most prominent tech companies are actively investing in JavaScript to reap its benefits. Full-stack development and the modern frontend framework continue to help JavaScript to stand out from other scripting languages.

JavaScript is a high-level interpreted language that is easier to learn and implement than any other programming language. In 2021, it is one of the best programming languages to learn if you want to develop internet applications and explore the fantastic opportunities of web application development.
