Testing patterns

Manually edit PatternComponent component and explore to http://localhost:3000/.

The render() method of PatternComponent must include <ChildComponent/> in its return value.

You will see that the following snippet forces a needless re-render of ChildComponent.

<ChildComponent prop={{}} />

In the following snippet, we refactor to prevent the needless re-render:

<ChildComponent prop={static_empty_object} />
