A comment on JavaScript async/await implemented in V8. Parent comment

Async/await is just syntax-sugar around Promises. No busy loops involved. (Those generally don't work in Javascript anyway.)

This overlooks Promises needing to be polyfilled. Though that's certainly not using busy loops either (though most of what I've seen overlooks more performant setTimeout(fn, 0) alternatives which is unfortunate).

Async/await already needs to be transpiled in for most browsers, so Promises needing to be polyfilled seems like the least of your problems.
