🖱️ Event Handling & 🧩 DOM Manipulation in JavaScript

JavaScript enables interaction with web pages through event handling and DOM (Document Object Model) manipulation.

🎯 Event Handling

Responding to user actions like clicks, key presses, or form submissions.

document.getElementById('myButton').addEventListener('click', function() {
  alert('Button clicked!');
});

🏗️ DOM Manipulation

Changing element content, styles, or structure dynamically.

const heading = document.querySelector('h1');
heading.textContent = 'Updated Heading';
heading.style.color = 'blue';

⚡ These techniques create interactive web experiences by reacting to user inputs and updating page content instantly.
