What is JavaScript?

JavaScript is a powerful, high-level programming language used to make web pages interactive and dynamic. Unlike HTML and CSS, which structure and style a webpage, JavaScript brings it to life — allowing users to click buttons, submit forms, play videos, show animations, and much more.

It is one of the core technologies of the web, along with HTML and CSS, and is supported by all modern web browsers without needing any additional tools or plugins.

✅ Key Features of JavaScript:

• Client-Side Language: Runs directly in the user’s browser.
• Dynamic Interactivity: Enables features like image sliders, popups, and real-time content updates.
• Lightweight & Fast: Executes quickly and integrates well with HTML/CSS.
• Versatile Use: Can also be used on the server side using tools like Node.js.

🎯 Why JavaScript Matters:

• Essential for front-end development
• Used by popular frameworks like React, Angular, and Vue
• Plays a major role in modern web apps, mobile apps, and even desktop software

💡 In simple words: JavaScript is what makes websites do things — like reacting to your clicks, validating your forms, or loading new content without reloading the page.
