What is JavaScript?

JavaScript is a programming language used to create dynamic content on websites. It allows you to control things like interactivity, animations, and data manipulation in your web pages.

Variables

In JavaScript, variables are used to store data values. You can declare a variable using let, const, or var.

let x = 5;
const name = "John";

Functions

Functions are reusable blocks of code. They allow you to group code that performs a specific task.

function greet(name) {
    return "Hello, " + name;
}

Events

JavaScript is often used to handle events, such as clicks, mouse movements, or keyboard actions.

For example, you can use the onclick event to trigger a function when an element is clicked.
