The only main difference is default print width. Other than that it should not produce massive diffs.

I'm using tsgo + oxlint + oxfmt for the first time.
It's all *so fast*. Small project (~1k loc, ~10 files), but type checking in 90ms, building in 60ms, linting in 70ms, and formatting in 80ms is fantastic.
🚀 The future of web dev tooling is bright. Nice work @typescriptlang.org and @voidzero.dev!
