Waiting for a pause in RxJS
RxJS interview exercise on Timing, difficulty 2 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write settled(source$, ms): emit a value only when ms milliseconds pass with no newer one; a newer value replaces the pending one. On completion, emit what is pending immediately.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Progress is saved in your browser, and in your account if you sign in.
