React.js Engineering Curriculum & Assessment Blueprint
Structured skill progression designed to prepare engineers for technical interviews and production delivery.
Fundamentals & JSX
Focuses on component composition, JSX transpilation, props immutability, local component state, event handlers, and list key reconciliations.
Hooks & Side Effects
Focuses on useEffect lifecycle synchronization, avoiding race conditions with AbortController, referential equality with useMemo and useCallback, and custom hooks.
Architecture & Scale
