javascript - When I removing markers from Here map, do I need to remove handlers? -

i'm using here map api, javascript. have map dynamically created markers. every time marker added adding eventlistener each marker. question: when removing marker map, need remove manually eventlisteners marker?

short answer yes, because removing marker won't remove attached event listener. therefore, if don't take care of listener, end memory leak.

that said, better have 1 event listener markers. can attach single listener on map, or on clustering provider if using clustering.
