Introduction to JavaScript

What is JavaScript?

JavaScript is a powerful programming language that helps bring websites to life! Unlike HTML and CSS, which control structure and style, JavaScript lets you make web pages interactive and dynamic. Whether you're building a game, animating an image, or creating a cool button effect, JavaScript is the tool for the job.

Where is JavaScript Used?

JavaScript runs in your web browser and powers most of the interactive features you see online. It's supported by all modern browsers and is a cornerstone of web development.

Key Features

  • Runs in the browser
  • Easy to learn and use

  • Used for both small tweaks and big web apps

Simple Example

alert("Hello, world!");

This code pops up a message box saying "Hello, world!" when you visit a web page.
