Async in TypeScript: interview exercises
Async in TypeScript: 4 test-checked interview exercises (Fetch in parallel, Retry a failing call), each beside a worked example, with tests as you go. Free.
- Fetch in parallel
- Retry a failing call
- Run tasks one at a time
- Add a timeout to a promise
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.
