Fun world of JS!

What is JavaScript?

  • JavaScript is a programming language designed for the web.

How is JavaScript used?

  • JavaScript is used to manipulate HTML and CSS.

  • It can also calculate, manipulate and validate data.

What is the difference between JavaScript and NodeJS?

  • JavaScript also called Vanilla JavaScript, is a programming language for the web.

  • NodeJS is an environment to run javascript apart from running on the web.

Which one are we going to learn?

  • Since this is the basics of JavaScript, it wouldn’t matter if it’s Vanilla JS or NodeJS.

Environment Setup for learning?

  • The easy way of executing JS can be done right into your browser’s console tab.

  • The second way is to go to NodeJS Website and download the “LTS” version of it.

  • If you went with the second way you need a code editor to write code. I suggest Visual Studio Code.
