You've noticed that a component re-renders frequently, causing performance issues. Which React feature can help you pinpoint unnecessary renders and optimize them?
- PureComponent
- shouldComponentUpdate()
- useCallback()
- useMemo()
To pinpoint and optimize unnecessary renders in React, you can use the shouldComponentUpdate() lifecycle method. This method allows you to implement custom logic to determine if a component should re-render or not based on the changes in props or state. While useMemo() and useCallback() are helpful for memoization and optimizing function components, PureComponent is a class component optimization and may not provide the same level of control as shouldComponentUpdate().
