JavaScript is the language of the web, in very simple terms JavaScript is a tool for developers to add interactivity to websites. It is a scripting language that is inserted directly in HTML of a page, in fact, it was the only programming language that could be understood by web browsers. In the 2019 Developer Survey done by Stackoverflow, JavaScript pretty much came out on top in terms of how powerful it is to create web applications. In 2017 Firefox 52 became the first web browser to support WebAssembly, which is a low-level programming language.
