Optimize Website Performance with Passive Pointerdown Event Listeners

The pointerdown event can be made passive using the ' {passive: true}' option in the addEventListener function. This helps to improve the performance of the website by allowing the event listener to run more efficiently and without causing any delays or disruptions.

Passive event listeners are used to make scrolling and touch interactions smoother and faster. By setting the passive option to true, the browser knows that the listener will not prevent default actions, such as scrolling, and will not block the UI thread.

Here is an example of using the passive option with the pointerdown event:

element.addEventListener('pointerdown', handlePointerDown, {passive: true});
