feat: enable biome recommended linter rules #9848

anonrig · 2023-12-14T16:16:22Z

Please review with caution and make sure you go through all lines.

Found several bugs on Biome:

I think we should enable some of these rules after this PR is merged:

Number.isNaN is not supported by IE11 😬 so we need to remove that rule and revert these, sadly, at least until V8!

I am not 100% sure if it is safe to replace these with anonymous functions - we should just double check, I remember seeing some comments somewhere that in some cases this may be tricky.

We need to exclude this file, as this is specifically copy-pasted from the sentry repo (where the loader actually lives), and should be exactly the same as there!

OK, I wont repeat this anymore, but for everything that's not node only we can't use Number.isNaN 😅
