@ahejlsberg I think you're working on pragma parsing, not sure what you're modifying at this point, though. Maybe it'd be fine to take this and you just delete the ported code in favor of your regex-free version?

[jakebailey]

This seems correct to me, just, bad timing with Anders porting more pragma code for JSX.

If this is in-progress I'm happy to wait. Support for @ts-nocheck is the only thing preventing me from using tsgo atm.

Er, well, we don't have JSDoc support, so JS support is going to be wonky at best.

Even though tests are passing locally, when I try using the built tsgo on my project.. its still reporting errors for files with // @ts-nocheck at the top. Not immediately clear to me why.

Alright I have this working to my satisfaction. If there are other PRs I need to resolve merge conflicts against, lmk.

Looks great, thank you!
