There does not appear to be a section called "Reusable Components" in the React documentation

In problem #2 for the "Setting State" exercise, it says to look up a guide called Reusable Components in the React Documentation, and to read a section called "No Autobinding". This does not seem to still be in the documentation.

I found this from an old version of the docs: https://zhenyong.github.io/react/docs/reusable-components.html
