If you want to do anything useful with Redux, the Redux docs are pretty terrible.
I hate any docs that are written in "step" form rather than "book/info" form.
I search for a specific thing I want to learn about and apparently it's skipped over because it's not "a commonly used thing".
The tutorial is OK-ish, but the reference docs are weak. If I have a specific question about some detail of the language, the answer is very rarely there.
Sometimes the answer is written up in the bug-tracking system or an RFC. They don't seem to have a culture where someone making a behaviour change, or a language-definition decision, is expected to update the reference manual at the same time.

We actually do have that as a literal rule [1], but since we’ve started from a place where the reference is incomplete, we can’t block everything on fully filling out every last detail. It’s being actively worked on though!
1: the rule has been slightly relaxed in the last few months for reasons; now a bug must be filed, rather than writing out the literal text. They usually get done fairy shortly after though.
