Conclusion

You can also declare event handlers inline:

App
<script>
	let m = $state({ x: 0, y: 0 });

	function onpointermove(event) {
		m.x = event.clientX;
		m.y = event.clientY;
	}
</script>

<div
	onpointermove={(event) => {
		m.x = event.clientX;
		m.y = event.clientY;
	}}
>
	The pointer is at {m.x} x {m.y}
</div>
<script lang="ts">
	let m = $state({ x: 0, y: 0 });

	function onpointermove(event) {
		m.x = event.clientX;
		m.y = event.clientY;
	}
</script>

<div
	onpointermove={(event) => {
		m.x = event.clientX;
		m.y = event.clientY;
	}}
>
	The pointer is at {m.x} x {m.y}
</div>
