Context & reducers in React: interview exercises
Context & reducers in React: 5 test-checked interview exercises (Context with a hook, A reducer), each beside a worked example, with tests as you go. Free.
- Context with a hook
- A reducer
- A context with a working default
- A store from context and a reducer
- Undo and redo with a reducer
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
