Answer
Memory leaks occur when unused objects remain referenced.
- Dangling references
- Uncleared timers
- Unremoved event listeners
- Closures holding unnecessary data
Remove listeners, clear intervals, and nullify unused references.
Quick Answer
Memory leak sources: global variables accumulating data, event listeners added without removal (document.addEventListener used with dead references), closures accidentally holding large objects, timers (setInterval) never cleared, and detached DOM nodes held by JS variables. Fix: remove listeners when done, clear intervals, don't store large objects in globals.
