Answer
JavaScript uses automatic garbage collection. Developers must avoid leaks by cleaning listeners, closures, and timers.
Quick Answer
JS uses garbage collection — the GC automatically reclaims memory for objects with no references. Allocations happen implicitly when you create objects. Memory leaks occur when references are accidentally kept: global variables, event listeners never removed, closures capturing large objects, or timers/intervals never cleared. Use Chrome DevTools heap snapshots to find leaks.
