What Is JavaScript?

Before diving into the best websites to learn JavaScript, let’s look at a brief overview of what JavaScript is and what it’s used for!

JS is a client-side language that executes in the browser (e.g., Chrome, Safari, FireFox). It is commonly used in web development alongside HTML and CSS. But it can also run server-side with platforms like Node.js, which makes it super unique and versatile. 

Another thing that makes JavaScript so appealing and popular among developers is that it comes with tons of libraries and frameworks that help you code more quickly, easily, and efficiently.

Overall, JavaScript is a hugely popular, in-demand, and easy to learn language! Read this for a crash course in JavaScript and how it works.
