Key Insights

Please provide the YouTube transcript you wish me to summarize.

Concept Check

When should you use useCallback?

Prevent unnecessary re-renders.

Always for performance.

Never, use useMemo instead.

Only with useState.

What's the main benefit of useMemo?

Simplifies state updates.

Handles asynchronous actions.

Memoize expensive calculations.

Reduces component renders.

How does useReducer manage state?

Directly, like useState.

Through a callback prop.

With a reducer function.

Using only context API.

When is useReducer preferred over useState?

Performance optimization.

Asynchronous operations.

Simple state changes.

Complex state logic.
