"No New Features" enables gradual React updates from older versions. React Hooks are an approach to state and lifecycle management in a React application without relying on class-based React components. [17] useState and useEffect, which are the most commonly used, are for controlling state and side effects respectively. Declarative views make your code more predictable and easier to debug. Hooks should only be called from React function components and custom hooks, not normal functions or class components.
