The pointerout event is fired for several reasons including: pointing device is moved out of the hit test boundaries of an element; firing the pointerup event for a device that does not support hover (see pointerup); after firing the pointercancel event (see pointercancel); when a pen stylus leaves the hover range detectable by the digitizer.

Using addEventListener():

document.addEventListener('pointerout', (event) => {
  console.log('Pointer moved out');
});

Using the onpointerout event handler property:

document.onpointerout = (event) => {
  console.log('Pointer moved out');
};
