Once you’ve got some basic knowledge about HTML, you’ll want more interactions with your users. This is where JavaScript is helpful. Describing the rules to validate some fields, changing the background color of a textbox to capture user attention or scrolling a page as the mouse cursor glides to the edge of the window…all of them are possible because of JavaScript.

The primary intent of JavaScript is web pages development (often called front-end development): defining the interactions within a web document (programmed with HTML). But today JavaScript is everywhere. From mobile applications (React Native, Ionic, PWA), desktop apps (Electron) or even server-side development (Node.js).

No wonder JavaScript is still trendy (see developer interests over time below). If there is only one language you’d need to learn in your life as a developer, this is it. Fortunately, this isn’t true, and you’ll have to learn a bunch of other languages :P.

Mastering JavaScript is a matter of lifetime. We’ve seen developers with tens of years of experience and still aren’t experts. There is such tremendous diversity in the JavaScript world (frameworks to be used, styles of programming, types of apps) that makes it challenging to cover by only one unique person. In fact, this is also true with less popular technologies already. That’s why, if you come for other very well structured and regulated fields, you’ll need to redefine the definition of expert (in IT).

Is there anything that might deprecate JavaScript? The same as for HTML and CSS, there is a chance that WebAssembly might challenge dramatically the web development world, in a sense of reinventing it in the upcoming 5 years. We believe they’ll complement each other.

About JavaScript

JavaScript (), often abbreviated as JS, is a high-level, interpreted scripting language that conforms to the ECMAScript specification. JavaScript has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions. Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web. JavaScript enables interactive web pages and is an essential part of web applications. The vast majority of websites use it, and major web browsers have a dedicated JavaScript engine to execute it. As a multi-paradigm language, JavaScript supports event-driven, functional, and imperative (including object-oriented and prototype-based) programming styles. - read more on Wikipedia
