Retry with a pause in RxJS
RxJS interview exercise on Errors & completion, difficulty 3 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write retryWithDelay(source$, count, ms): on error wait ms milliseconds, then try again, up to `count` retries; then let the error through. A success in any attempt passes its values through as usual.
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.
