React top latest feature

1. React Hooks: Hooks were introduced in React 16.8 as a way to use state and other React features without writing a class. They allow you to reuse stateful logic between components, enabling a more functional approach to building React components.

2. Context API: React's Context API allows you to share data across a component tree without passing props manually at every level. It provides a way to manage global state or share data that needs to be accessible by multiple components.

3. React.memo(): This is a higher-order component that memoizes the result of a component rendering. It allows you to optimize the performance of functional components by avoiding unnecessary re-renders when the component's props haven't changed.

4. React.lazy() and Suspense: React.lazy() is a built-in function that allows you to lazily load components, which means they are loaded only when they are actually needed. Suspense is a component that enables you to handle loading states while waiting for the lazy-loaded components to load.

5. Concurrent Mode: Concurrent Mode is an upcoming feature in React that aims to improve the responsiveness and performance of React applications. It allows rendering and updating components asynchronously, enabling smoother user experiences and better handling of complex UI interactions.
