You're building a dashboard that frequently updates with real-time data. Which feature of React would best help minimize unnecessary DOM updates?
- PureComponent
- React.memo()
- shouldComponentUpdate()
- useMemo()
To minimize unnecessary DOM updates in React, you should use the useMemo() hook. This hook allows you to memoize the result of an expensive computation so that it's only recomputed when its dependencies change. This is particularly useful when dealing with real-time data that frequently updates to avoid unnecessary re-renders of components.
