Intro to JavaScript

Welcome to the JavaScript tutorial series! JavaScript is the programming language of the web — it makes web pages interactive, dynamic, and alive. Every modern website you use relies on JavaScript.

What You Will Learn

Over 46 episodes we will cover every core concept you need to start writing JavaScript confidently:

• Variables, data types, and operators — storing and manipulating data
• Control flow — if statements, loops, and comparisons
• Functions — reusable blocks of code
• Strings, numbers, and arrays — working with different data types
• Objects — structuring complex data
• The DOM — interacting with HTML pages
• Events — responding to user actions
• Forms and validation — handling user input

Prerequisites

You should have a basic understanding of HTML and CSS before starting this course. If you haven't learned those yet, check out our HTML and CSS tutorial series first.
