Some people don’t always have a fast (or any) internet connection when they work. In those cases it can be nice to have offline versions. I imagine this is useful for a lot of people around the globe. I don’t use the broader internet a whole lot when I work, but I do use the official documentation pages when I forget how basic things, partly because my memory isn’t great but also because I work on multiple languages and don’t always remember how they each do specific things like splitting strings, reducing arrays or whatever. If I couldn’t just go to the official language documentation’s I’d need offline versions.
