Almost all modern websites use JavaScript, and all modern web browsers — on desktops, game consoles, tablets, and smartphones — include JavaScript interpreters, making it the most present programming language in history.

Its purpose is to infuse websites and web applications with interactivity! This can range from simple features, such as neat visual effects or displays of the current time and date, to more sophisticated use cases, such as data fetching, chatrooms, browser games, web servers, and even the creation of entire interfaces for things such as social media networks.

Because of this, JavaScript is one of three must-learn technologies for any web developer. You learn HTML to create your website's content, CSS to give it a fitting presentation, and JavaScript to make it come to life!

JavaScript is Everywhere

Where can you find websites that use JavaScript? It would be harder to find the ones that don’t!

Did you watch a show on Netflix recently? Several JavaScript frameworks were used to build the applications' interface and achieve quicker startup times!

What about PayPal transactions? Did you know their site uses JavaScript for various components of its checkout system?

Have you ever visited an impressive portfolio, with images flying in and out of view based on how far down you scroll and elements gradually popping in and out as you make your way through the site? That was most likely done with JavaScript, as well.

Do you have a Facebook profile? Watch YouTube videos? Check out what’s new on Instagram? Scroll through TikTok? Chat with people on WhatsApp?

All of these most popular apps are built using JavaScript. It’s used in almost every area of software development today. It's not just for websites anymore; JavaScript powers desktop apps, mobile apps, servers, and even IoT devices. Discord is an excellent example of its omnipresence.

Discord’s web app is made with React, a JavaScript framework for building user interfaces.

Discord’s desktop app is made with Electron, which ported its web app features to your desktop app using JavaScript.

Discord’s mobile apps for iOS and Android are built using React Native, which allows you to use your JS skills to build mobile apps!

Discord's servers and bots are also programmed with JavaScript, showing just how flexible it is.

JavaScript is leading the pack, from web apps and servers to desktop and mobile apps.

It is everywhere!
