Try again in RxJS
RxJS interview exercise on Errors & completion, difficulty 2 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write retrying(source$, times): on error, subscribe to the source again, up to `times` more attempts; if it still fails, let the error through.
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.
