World 2 / Builder Zone
Practice debugging real React Native issues: error reading, debug panels, validation test cases, component scenarios, counter bugs, stable list keys, error boundary concept and a final Debug Lab App. Clear lessons to unlock next zone. Boss Project waits at the end.
The dungeon trains precision: forms, validation, errors, and resilience when the app breaks.
