As we’ve briefly seen already, you can listen to any DOM event on an element (such as click or pointermove) with an on<name> function:
App
<div onpointermove={onpointermove}>
The pointer is at {Math.round(m.x)} x {Math.round(m.y)}
</div>Like with any other property where the name matches the value, we can use the short form:
App
<div {onpointermove}>
The pointer is at {Math.round(m.x)} x {Math.round(m.y)}
</div>previous next
