It's ungodly slow on large projects. I've been using `deno fmt` lately (despite not having any other use for deno), it reformat/checks thousands of files per second, and supports YAML too.

This says YAML support is behind an unstable flag, but I haven't been passing any flags. Works fine anyway.

Ha, I use Deno just as a formatter also! It’s great for Markdown formatting.

The package pretty-quick speeds up prettier significantly
