stages
* mounting
** componentWillMount()
** componentDidMount()
called after render() call (initial rendering of the component - DOM tree created)
* updating
** componentWillReceiveProps(nextProps)
** shouldComponentUpdate(nextProps, nextState)
returns true by default. if case of false, the next 3 method calls will be skiped
** componentWillUpdate(nextProps, nextState)
you can not use this.setState(...) here, use componentWillReceiveProps(...) instead
** render()
** componentDidUpdate(prevProps, prevState)
* unmounting
** componentWillUnmount
called just before unmounting
Notes
* forceUpdate() method forced the updating-stage, but without shouldComponentUpdate(...) call on a component, which triggered update
