Neat! Didn't know about this concept. Any more examples of this being used somewhere?

The technique discussed is a kind of inversion of control, a concept which has a pretty long history (~30 years according to the wikipedia article). I've been writing React for a couple of months now and had settled on this method without knowing it was considered new or in anyway unusual.

Other packages have been doing this for a while: react-virtualized, react-motion, react-form ... I wonder why the topic pops up seemingly every week

Using ReasonReact with ReasonML sort of forces you down this path due to its strong type system. It’s quite lovely once you get used to it.
