1.1k isn't bad for a project with ~33 million weekly downloads[1], imo. Yes, I know that's not necessarily a good metric, but it's ~10 million more than React[2] which also has a similar number of open issues[3].
A code formatter has no business having 1100 open issues (5k closed). It is not rocket science.
In my experience, the number of open issues not only correlates with popularity, but how crappy the language is. Javascript projects, with its myriad of dependencies and attracting junior, inexperienced devs, tend to accumulate a great number of bugs.
For reference, curl has 24 open issues (4k closed), it is a couple orders of magnitude more complex AND more used than prettier.
