Function components take in props, and return JSX. React also gives us another way of writing components using classes instead of ...
Class components have been the traditional way of creating components in React and are still widely used in many existing codebases. They offer a more familiar syntax for software engineers coming from object-oriented programming backgrounds and provide more fine-grained control over the component’s...
