Quick Answer
Prevent memory leaks in large jQuery apps: always clean up with .off() and .removeData() in teardown, use .remove() (not innerHTML clearing) so jQuery cleans up events/data, destroy plugin instances explicitly, clear intervals and timeouts, use WeakMap or .data() for element-scoped caches (not global variables), and use Chrome heap snapshots to track growing detached DOM trees.
