JavaScript Stats

Javascript is the KING of web development. The world’s top websites or web applications (Microsoft, Groupon, PayPal, Netflix) you see, and have been using every day are built on JavaScript. 

But it’s not just limited to web development because of its versatility. Web developers can use this programming language for mobile applications, server-side apps, desktops, and AI apps.  

But what makes it different from other programming languages? 

It meets the changing expectations of modern consumers by powering developers to create online applications that are full of dynamic experiences and interactivity. On top of that, users can’t live their future with bland and static websites that have no interactivity. 

Let’s discuss some of the important Javascript statistics, its usage, popularity, and what industries are leveraging it to its full potential. 

What is JavaScript? 

JavaScript everywhere

Brenden Eich introduced JavaScript in 1995 as a client-side programming language. It was earlier known as LiveScript. 

One of the most used programming languages in the world is JavaScript. It’s a scripting language that web developers use for creating web pages, applications, game servers, etc.   

They use it primarily for adding dynamic elements on websites that can’t be added with CSS or HTML. 

If you come across any dynamic element on the website, slideshows, or any other interactive feature, all THANKS to the JavaScript framework.  

JavaScript is becoming a popular scripting language for front-end web applications. This programming language is a game changer for developers as they can add interactivity to web pages, enable animation, and do real-time content updates.
