terminology is one of the many funny things about React, in this release:

> By convention, functions that use async transitions are called “Actions”.

React is the only people who use this "convention". They pick a very meaningless word for their terminology, but then they just can't stick with it and have to name the hook `useTransition` for some reason.

Instead of wasting doc space for sentences like above, why don't they just use the same word for the api and the concept? If you're gonna refer to the concept as "action", then the hook should be useAction. And if you think "action" is a meaningless word and you need to add some explanation about mutation or promises in the docs, then maybe better just call the concept "mutation", "async transition", whatever and same with the hook.
