I'll be honest, with the knowledge they are building their own type system and not adopting typescript, my interest went to near 0. Typescript has been a delight to use and migrating off of it is a non-starter. It will take a lot to get me to move off of using typescript even in greenfield projects.

I don't share your praise of typescript (native perf is terrible / it's not strict enough so I routinely get hit in production with type errors through the escape hatches) but you can very well use TS with Biome, I maintain a good number of TS services / apps using Biome and SWC (so I get decent performance).

Performance is also the reason I like Biome over eslint / prettier

Biome doesn't want to replace TypeScript.

I thought the same thing. Just another tool in the infinite list of tools in the JS ecosystem. No, thanks.

Why would you have to migrate off of TS?
