| // When the UI changes, it usually happens just in some parts of the screen. | ||
| // This means that most children with the same keys will likely render to the same output. | ||

This was a bit hard for me to read because of all the existing preconceptions about how React works.
As I read through this, I tried to annotate it with comments to help me (and maybe other people) understand what’s really going on here. Partial application with
