const moveHandler = function() {
// do something...
}
dom.addEventListener("mousemove", function() {
window.requestAnimationFrame(moveHandler)
})is there any difference between the two writing methods? This is the problem I encountered when dragging a dom effect
document.removeEventListener remove to drop the moveHandler event, but fragment B cannot; requestAnimationFrame whether it is an anonymous function or passing in a specific method, there is no difference personally, I think it is more recommended to write segment A:
1. removeEventListener
2.
3. --
in terms of the effect achieved, there is no difference
