Bring your web pages to life by learning JavaScript - the programming language of the web.
JavaScript is a high-level, interpreted programming language that enables interactive web pages. It lets you create dynamically updating content, control multimedia, animate graphics, and much more.
This tutorial covers the essentials of JavaScript programming, from variables to DOM manipulation.
Variables are containers for storing data values. JavaScript has let, const, and var variable types.
let name = "Alice";
const age = 30;
var city = "Paris";
A function is a block of code designed to perform a particular task.
function greet(name) {
return "Hello, " + name;
}
Edit the JavaScript code above, and the output will appear in the right panel.
Modern JavaScript introduces features like arrow functions, template literals, and destructuring assignment.
const greet = (name) => `Hello, ${name}`;
const user = { name: "Alice", age: 30 };
const { name } = user;
JavaScript allows manipulation of HTML elements, enabling dynamic web content.
document.querySelector("#demo").innerHTML = "Dynamic content!";
