Introduction to JavaScript 🌟

JavaScript is a dynamic programming language primarily used for web development to create interactive elements on websites. It runs in the browser and allows developers to add functionality to HTML pages. Here's a quick overview:

📘 Key Concepts

• Variables: Store data using let, const, or var

  let message = "Hello, World!";
  

• Functions: Reusable blocks of code

  function greet(name) {
    return `Welcome, ${name}!`;
  }
  

• DOM Manipulation: Modify webpage content dynamically

  document.getElementById("demo").innerHTML = "Modified content!";
  

• Events: Respond to user actions like clicks or form submissions

  button.addEventListener("click", function() {
    alert("Button clicked!");
  });
  

## 🚀 Applications
JavaScript is essential for:
- **Frontend Development** (e.g., animations, form validation)
- **Backend Development** (Node.js)
- **Mobile Apps** (React Native)
- **Games** (HTML5 Canvas)
