Makes sense.

I would still prefer though that Bun did it for me, in a separate process perhaps, so I wouldn't need to configure a separate CI job, or manually enter the tsc-command. I read that Bun has its own test-runner too so why not its own type-checker too.

On Node.js I just edit the source-code then re-start the debugger on it, and edit it while in the debugger then rinse and repeat.

I use runtime assertions to catch errors in argument-types etc. as needed.

the only time you run type-checker is on CI. For the majority of the time you only need the code to compute and your editor/IDE should already have its own bundled type-checker. Unless bun has its own type-checker which means it has to play catch-up with tsc (if that's even possible, typescript's type system is very complex), I don't find a lot of benefit for Bun to merely call tsc for me.
