Why is it recommended to avoid inline JavaScript and instead separate the behavior from the HTML elements?

It is recommended to avoid inline JavaScript because it can make the code harder to maintain and debug. Separating the behavior from the HTML elements improves code readability, reusability, and scalability. By keeping JavaScript separate, it also promotes a more organized and structured development approach.

<!DOCTYPE html>
<html>
<head>
    <title>Separating Behavior from HTML Elements</title>
    <script src="script.js"></script>
</head>
<body>
    <button id="myButton">Click Me</button>
</body>
</html>
```

script.js:
```javascript
document.getElementById('myButton').addEventListener('click', function() {
    alert('Button clicked!');
});
