What is the purpose of getDerivedStateFromProps() lifecycle method?

The new static getDerivedStateFromProps() lifecycle method is invoked after a component is instantiated as well as before it is re-rendered. It can return an object to update state, or null to indicate that the new props do not require any state updates.

    class MyComponent extends React.Component {
      static getDerivedStateFromProps(props, state) {
        // ...
      }
    }

This lifecycle method along with `componentDidUpdate()` covers all the use cases of `componentWillReceiveProps()`.
