Optimize React Components With React.memo For Better Performance
React.memo optimizes component performance by preventing unnecessary re-renders with shallow prop comparison or custom comparison functions, ideal for large lists, expensive components & performance optimization.
React.memo is a higher-order component (HOC) that helps optimize the performance of React components by preventing unnecessary re-renders. It is used to memoize functional components, which means React will skip re-rendering the component if its props haven't changed. This is particularly useful for performance optimization in large React applications where re-rendering may be costly. How React.memo Works React.memo works by performing a shallow comparison of the props of the component. If the props are the same as the previous render, React will skip rendering the component and use...
