Learn JavaScript
JavaScript is the magic that makes websites interactive! Learn how to create animations, respond to clicks, and build amazing web applications from scratch.
🤔 What is JavaScript?
JavaScript is a programming language that runs in your web browser. It's what makes websites do cool things like show popups, change colors, and respond when you click buttons!
Makes Websites Interactive
When you click a button and something happens, that's JavaScript! It listens for your actions and responds to them.
Essential SkillRuns Everywhere
JavaScript works in every web browser - Chrome, Firefox, Safari, and more. Write once, run anywhere!

You can see results instantly in your browser! No special software needed - just start coding and see it work.
Easy Start✨ Your First JavaScript Code
Let's write some real JavaScript! Don't worry if it looks strange at first - we'll explain every part step by step.
// This is a comment - the computer ignores it! // Comments help us explain our code // Let's say hello to the world console.log("Hello, World!"); // Create a variable to store your name let myName = "Student"; // Show a personalized greeting console.log("Welcome to JavaScript, " + myName + "!"); // Do some simple math let sum = 5 + 3; console.log("5 + 3 = " + sum); // Output: 5 + 3 = 8
🎯 Try It Yourself!

📚 Key JavaScript Concepts
Master these fundamental concepts and you'll be able to build amazing things!
Variables
Variables are like labeled boxes that store information. You can put numbers, text, or other data inside them.
let age = 25; let name = "Alex"; let isStudent = true;
Conditions (If/Else)
Make your code smart! Conditions let your program make decisions based on different situations.
if (age >= 18) { console.log("Adult"); } else { console.log("Minor"); }
Loops
Need to repeat something? Loops run the same code multiple times automatically. Very useful for lists!
for (let i = 1; i <= 5; i++) { console.log(i); } // Prints: 1, 2, 3, 4, 5
Functions
Functions are reusable blocks of code. Write once, use many times! They help keep your code organized.
function sayHello(name) { return "Hello, " + name; } sayHello("World");
Arrays
Arrays store multiple items in a single variable. Perfect for lists of things like names, numbers, or items.
let fruits = ["apple", "banana", "orange"]; console.log(fruits[0]); // apple console.log(fruits.length); // 3
Events
Events happen when users interact with your page - clicking, typing, scrolling. JavaScript can respond to all of them!
button.addEventListener("click", function() { alert("Button clicked!"); });
