Model updating

Posted by / 01-Apr-2020 13:02

If you don’t initialize state and you don’t bind methods, you don’t need to implement a constructor for your React component.

In rare cases, it’s okay to initialize state based on props.

This effectively “forks” the props and sets the state with the initial props.

Error boundaries catch errors during rendering, in lifecycle methods, and in constructors of the whole tree below them.Code reuse is primarily achieved through composition rather than inheritance in React.Take a look at these common scenarios to get a feel for how to use composition.Only use error boundaries for recovering from unexpected exceptions; don’t try to use them for control flow.For more details, see enqueues changes to the component state and tells React that this component and its children need to be re-rendered with the updated state.
