You can check here

https://github.com/javascriptdata/danfojs/blob/76386815061436f031fb778c9a1e4595077a3812/src/danfojs-base/core/series.ts#L834

And you can dropna and then sort

I need the rows with NaN though, because the other columns have usable values. It would make sense if the NaN values were all together somehow, at the start or the end.

I am seeing the same issue with DataFrame sortValues function.

I don't think there's an active maintainer on this repository. It's a shame, it's the best one similar to Pandas that I've found.
