React.Component vs React.PureComponent ??
whether the fundamental difference between them

Can you include a valid argument ...
I look at react 1.5 , even though we use the Component directly [extends Component], they will automatically do checked / deep equal check in state change before decide to rerender the components

Have you seen the docs?

If your React component's render() function renders the same result given the same props and state, you can use React.PureComponent for a performance boost in _some cases_.

See #811 for more.

since our state base on redux state... PureComponet is better for performa
PureComponet = Shallow check when props arrived
