react extend functional component

We use as little TypeScript as possible. Hooks are a new addition in React 16.8. The lifecycle methods below are marked as “legacy”.

In general, hooks allow to “attach” behavior to a functional component without the need to write classes, create wrappers or use inheritance. If you need to set the state based on the previous state, read about the updater argument below. It is very inefficient and will harm performance. Once a component instance is unmounted, it will never be mounted again. You should not call setState() in componentWillUnmount() because the component will never be re-rendered. It receives two parameters: componentDidCatch() is called during the “commit” phase, so side-effects are permitted. We all know with React, we can make components using either classes or functions. Functional components are my most favourite thing in React. If you’d like, you can reuse some code between getDerivedStateFromProps() and the other class methods by extracting pure functions of the component props and state outside the class definition. They let you use state and other React features without writing a class. For those use cases, use componentDidMount() instead. Create a Class Component. It should not be directly mutated. For example,
