how about the asynchronous calls?

[ronniegong]

as i see, this can measure the synchronous methods cost
but what about the asynchronous calls, such as fetch/promise call?

The idea is to measure things that affects performance (lowers fps, jank, etc.) and usually these are as a result of hogging the main thread and doing things synchronously. If you have a solid idea how to benefit from measuring async calls, feel free to submit a PR with your implementation and I could take a look.
