JavaScript is a programming language that makes websites dynamic and interactive. Unlike HTML and CSS, which define structure and style, JavaScript brings websites to life.
Why Learn JavaScript?
- It powers most modern websites.
- Helps in creating interactive features like forms and buttons.
- Works with frameworks (React, Angular, Vue) for advanced apps.
Example of JavaScript
<button onclick="sayHello()">Click Me</button>
<script>
function sayHello() {
alert("Hello, welcome to JavaScript!");
}
</script>
Key JavaScript Concepts
- Variables → Store data.
- Functions → Reusable blocks of code.
- Events → Respond to user actions.
- DOM Manipulation → Change page content dynamically.
Conclusion
JavaScript makes your websites smarter and more engaging. Start small with buttons and alerts, then move toward games and interactive apps.
