There is also the async version of this function, and I think it allows using await in config files.

Ah, I assumed there wasn't as it's not in the types 😅

Uh it's because the types are not maintained by us.
We are slowly converting our codebase to TS, we'll release official type definitions when we finish.

not too happy about this one 🙁 We should output ESM from Jest 28 or something

I think adding export { createTransformer } to babel-jest would be enough.

yep that'd work, but "real" ESM should use a single default export of an object, so the issue is a "fake" esm module imported directly in native ESM. Edge casey enough that I don't think it's worth changing before just using native ESM

Oh, and just to be explicit - the .default change is not because of this PR, but the change made in #11193

Test plan
Not sure... I've verified via some inserted
console.logs that it works. Not sure how to write a test. (marked as draft due to this)EDIT: copied the synchronous test 🤷 Also added an e2e test
