Go's stdlib mistakenly sorted files by default on directory walks(with no option to not sort them). This of course means a directory must be fully iterated on before you can process or bail out of processing. I wonder if Deno ported this directly or reworked it.
There are some other issues with file stats as well; requiring multiple syscalls to retrieve information that can be had in just one.
It's a mystery to me why they made such a high level decision in such low level code without an escape hatch.. Been a lot of talk but probably won't be fixed any time soon due to backwards compatibility.
readdir is problematic in ways godirwalk works around.
Of course one could always just make direct syscalls or use a library that does, but this was a comment about stdlib. These would likely be implemented differently in hindsight per discussions on the Go project; and there have been discussions about improving them somehow in Go 2(readdir2?).
