Variables: let, const, var
Data Types: String, Number, Boolean, Object, Array
Operators: +, -, *, /, %
Conditionals: if, else if, switch
Loops: for, while, forEach

    alert('Button clicked!');
});

4. Combining HTML, CSS, and JavaScript

A professional website is created by combining all three technologies:

HTML – Structures the content
CSS – Styles the content

}
</style>
<script>
document.getElementById('btn').addEventListener('click', function() {
  alert('Hello, world!');
});
</script>
