JavaScript written directly inside <script> tags is called inline JavaScript. It is parsed and run immediately when encountered.
Inline scripts are fine for small snippets but should be moved to external files as the codebase grows.
<script>
document.addEventListener("DOMContentLoaded", function() {
var btn = document.getElementById("myBtn");
btn.addEventListener("click", function() {
alert("Button clicked!");
});
});
</script>Avoid mixing HTML and JavaScript logic — keep behavior in separate JS files.
