Top level await

[mstoykov]

What?

top-level-await support

Why?

It is part of the specification and it is hepful if you have async APIs ... which k6 starts to get more and more off.

Took it for a spin locally, and you have no idea how having the ability to do this:

import { open, SeekMode } from 'k6/experimental/fs'

const file = await open('package.json')

export default async function () {
  // ...
}

Makes me happy! Great job @mstoykov, thanks a lot for making this happen, much appreciated! 🙇🏻 🎉 🚀

The base branch was changed.

It's worth updating also examples (like experimental/fs) and documentation to reflect the change 👍
