1. Leaking instance state into Klasses
2. Improper setup/teardown of the event listeners
3. Stashing state in global or module scopes
4. Saving non-primitive property of controllers to non-singleton objects
5. Failing to destroy the third party widgets when the component is unmounted
6. Closure leaks
   • setInterval
7. Saving non-singletons components into singletons controllers/services
