Answer
State is managed using hooks (React useState/useReducer), global stores like Redux/MobX, Angular services with RxJS, or NgRx. Centralized state prevents prop drilling and ensures predictable UI updates across large apps.
Quick Answer
Component state in frameworks: local state (useState in React, ref/reactive in Vue, signal in Angular) for component-specific data. Lifted state for shared parent-child data. Global store (Redux, Pinia, NgRx) for cross-component shared state. Derive state computationally (useMemo, computed) instead of duplicating. Keep state as close to where it's used as possible.
