A top-level App component returns <Button /> from its render() method.

1. What is the relationship between <Button /> and this in that Button’s render()?

2. Does rendering <Button><Icon /></Button> guarantee that an Icon mounts?

3. Can the App change anything in the Button output? What and how?

Important: At the time of writing (2019-11-11) Immutable.js is effectively abandonware, so I can no longer recommend anyone to follow the advice given here. I'll leave the article here for posterity, since it's still getting some traffic.
