The quiz and summary section of chapter 3 refer to componentDidMount / componentWillMount, however these topic are not covered in this chapter.

They are included in the Mixin code in chapter 4 but not defined until chapter 6.

Also, chapter 6 mentions "componentDidUnmount" but there's no such call. It should be "componentWillUnmount."

To quote the react code itself:

* NOTE: There is no `componentDidUnmount` since your component will have been
* destroyed by that point.
