🐛 Bug Report

Async Iterators or generators simply don't work with jest even thought they're natively supported in Node 10

To Reproduce

0. Install Node 10.x.x
1. cd to a test project where jest works
2. add async function* foo() {} to some file
3. run your project (with yarn start or node index.js etc.)
4. Notice that it works
5. Try running your test cases yarn test
6. Notice that jest complains about "unexpected token *"

Expected behavior

The test suite should run normally and not throw this error

Link to repl or repo (highly encouraged)

Seems like repl.it doesn't have node 10. Sorry :/

Issues without a reproduction link are likely to stall.

Run npx envinfo --preset jest
