 `componentWillReceiveProps()` is invoked before a mounted component receives new props. If you need to update the state in response to prop changes (for example, to reset it), you may compare `this.props` and `nextProps` and perform state transitions using `this.setState()` in this method.

 React doesn't call `componentWillReceiveProps()` with initial props during [mounting](#mounting). It only calls this method if some of component's props may update. Calling `this.setState()` generally doesn't trigger `componentWillReceiveProps()`.
