Implementation decisions
- 1Identify the owning component, hook, route, store, or service.
- 2Define inputs and outputs before adding framework helpers.
- 3Keep render logic pure and isolate external synchronization.
- 4Choose behavior that remains correct during rerender and unmount.
Verification plan
- 1Test the primary Why Learn React? behavior, one boundary, and one failure. Include a check for these focus terms: why, learn, react, reference R39649A.
- 2Check loading, empty, success, and failure behavior when applicable.
- 3Confirm keyboard and screen-reader behavior for visible UI.
- 4Profile only after correctness tests pass.
Practice task
- 1Build the smallest Why Learn React? example.
- 2Introduce this failure: Treating Why Learn React? as generic UI code hides its actual contract. In this lesson, watch the focus terms: why, learn, react, reference R39649A.
- 3Correct it using this rule: Define what Why Learn React? owns, receives, changes, and returns. Use the focus terms (why, learn, react, reference R39649A) to keep the implementation tied to this exact lesson.
