JavaScript for Beginners 02 – What is JavaScript?

Hey guys, welcome to your 2nd JavaScript tutorial for beginners. In this lesson we’ll take a quick look at what JavaScript actually is, and how it differs from other programming languages.

JavaScript is what’s known as a client-side language, meaning it runs on your computer and not on a web server. There are exceptions to this (e.g. with Node.js) but this is generally the case. Other programming languages such as PHP, run on the server and are called server side languages.

JavaScript is also a scripting language. This essentially means it is limited in functionality – but this is the way it was made, intentionally! It’s primary purpose is to add functionality and interactivity to websites, such as banner sliders, zoom-galleries, drag and drop etc.
