What does the React.memo function do?
- Improves memory usage by storing data more efficiently.
- Prevents unnecessary re-renders of functional components.
- Converts class components into functional components.
- Enhances CSS styling in React applications.
React.memo is used to prevent unnecessary re-renders of functional components. When a functional component's props or state change, React will re-render it. React.memo optimizes this process by memoizing the component, so it only re-renders when its props change. The other options do not accurately describe the purpose of React.memo.
