How to listen to state changes?
componentDidUpdate lifecycle method will be called when state changes. You can compare provided state and props values with current state and props to determine if something meaningful changed.
componentDidUpdate(object prevProps, object prevState)
Note: The previous releases of ReactJS also uses
componentWillUpdate(object nextProps, object nextState) for state changes. It has been deprecated in latest releases.
