State Management with useState
State is data that belongs to a component and can change over time. When state changes, React re-renders the component to reflect the new state.
useState Hook
The useState hook is the primary way to add state to functional components. It returns an array with two elements:
- 1. The current state value
- 2. A function to update the state
State Updates
- • State updates are asynchronous
- • State updates trigger re-renders
- • Multiple state updates in the same function may be batched
- • State should be updated using the setter function, not by direct mutation
Best Practices
- • Use descriptive state variable names
- • Initialize state with appropriate default values
- • Use functional updates when the new state depends on the previous state
- • Consider splitting complex state into multiple useState calls
