Master mapped type form state
Insane TypeScript arena: mapped types, keyof, partial updates, and readonly data
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: typescript-easy-mapped-types
A settings form needs typed dirty-state tracking for every field. You are working inside a TypeScript monorepo, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply mapped types, keyof, partial updates, and readonly data in a TypeScript monorepo while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates mapped types, keyof, partial updates, and readonly data
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Clear the route first
You can read the mission brief, but the editor, hints, tests, and submit flow stay locked until progression or plan access catches up.
