I like kubernetes.io docs. You can learn from tasks, concepts, tutorials and docs itself.
The Vue.js website has superb documentation. Definitely props to the Vue team.
I am missing rust
also redux
unity is not bad either
lets see how long this thread going to be.
The React Docs are really great because they are concise and offer a good mix of completely documenting the interfaces and specialties (some might call them quirks) of the framework and offering higher-level advice of how to structure your application, also keeping performance in mind etc.
The docs and blogs around VS Code are also usually quite good and I love reading their changelogs (because they usually offer a lot of new features and present them well with screenshots/gifs).
Django, hands down. Golang is also really good. Heroku also provides excellent tutorials and reference.
Mozilla developer docs.
Is quite as good as the Delphi Docs from Borland back in the days.
There is also the Go language which is itself writen in Go, in VSCode you can go to the definition and see the internal code and documentation. That is so cool, but maybe isn't what you are asking for...

From all of document I've read, I think PHP document is the one I could easily understand. Moreover, it got comments in almost every pages which sharing lot of useful tips.
Don't like the language very much but I do like their docs. I wish C++ has one.
I think I get less than 20% of my information from documentation.
For reading large sections, books or blog posts are usually more convenient.
For searching specific answers, Google and StackOverflow (or Hashnode) are usually more convenient.
The role that documentation does fill is having long lists of all options. But I don't often want to know what options are available, I usually want to know which option I need to achieve something.
DB2 and ifort stood out to me as having bad documentation.
I'm not a PHP developer but I've seen that Laravel has a very nice documentation. And Vue.js that is inspired on it too. I also like the CockroachDB docs, they serve as a general SQL documentation too 😊
