Where HTML is the structure of your website, and CSS is the beauty and design, JavaScript is the functionality and “doing” of your website. Other than for building web frontends, JavaScript is now used extensively in back ends through systems like NodeJS, and in scripting languages for game development tools like Unity. Compared to a compiled language like C#, JavaScript becomes interpreted by the device at the time of it’s running. Being the most known programming language by developers, JavaScript is not going anywhere and we love it here at Lightwood Solutions.
