Adding JavaScript to HTML

• Inline Script: Add JavaScript directly to an HTML element using the onclick or similar attribute.
• Internal Script: Place JavaScript code inside a <script> tag within your HTML file.
• External Script: Write JavaScript in a separate .js file and link it to your HTML.

• Inline: <button onclick="alert('Clicked!')">Click me!</button>
• Internal:

  <script>
    alert('Hello from internal script!');
  </script>

• External:

  <script src="script.js"></script>

  // script.js
  console.log('Hello from external file!');

Tip: External scripts are best for big projects and code reuse!
