<!-- Best practice -->
<button id="btn1">Click me!</button>
<script>
	document.getElementById("btn1")
		.addEventListener("click", function() {
			window.alert("You clicked me!");
		});
</script>
<!-- Still valid, but prefer the above over this -->
<!-- (the above allows multiple and you can never 'overwrite' an event listener) -->
<button id="btn2">Click me!</button>
<script>
	document.getElementById("btn2")
		.onclick = function() {
			window.alert("You clicked me!");
		};
</script>
<!-- A different version of the previous -->
<button id="btn3" onclick="btn3ClickHandler()">Click me!</button>
<script>
	function btn3ClickHandler() {
		window.alert("You clicked me!");
	}
</script>
