react-video-render-prop 
React render props, what are they?
After reading this PR facebook/react#10741 I wondered what the benefits were.
TL;DR: It's a slightly different way of getting child state visible in the parent component.
The only slight issue I had was getting coverage on 'just' the unit, my usual workflow has me mocking subcomponents. The child component had to render in order to exercise the inline component in the parent's render function.
