Introduction to JavaScript

JavaScript is the magic behind interactive websites! It’s a programming language that runs in your web browser, making pages dynamic and fun. Without JavaScript, websites would be as lively as a printed book.

• It can show pop-up messages.
• It can change images, colors, and text on the fly.
• It can fetch new data without reloading the page.

• It’s everywhere: 98% of websites use it!
• It’s beginner-friendly and forgiving.
• It opens doors to web, mobile, and even server programming.
