AngularJS - Timer Application
Create and clean up a timer while avoiding stale callbacks and memory leaks.
How it works
Timers should store their handle and cancel it when a view is destroyed. Account for delayed callbacks and page suspension; derive elapsed time from timestamps rather than assuming every interval fires exactly on schedule.
Practice checklist
- Use examples that match the AngularJS version in the existing application.
- Keep user input, asynchronous states, and failures visible and understandable.
- Test keyboard access and validate important rules on the server.
- Review dependency support and migration needs before production changes.
