support async iterables (for await...of)

[ungoldman]

What version of this package are you using?

14.3.4

What problem do you want to solve?

Example code from core fs docs does not pass standard lint:

const fs = require('fs')

async function print (path) {
  const dir = await fs.promises.opendir(path)
  for await (const dirent of dir) {
    console.log(dirent.name)
  }
}
print('./').catch(console.error)

Parsing error: Unexpected token await

What do you think is the correct solution to this problem?

Async iterables (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for-await...of) have made it to the spec and are part of the core docs as of at least node v12.12.0.

standard should be able to recognize them and let them pass 🧙

Are you willing to submit a pull request to implement this change?

Maybe

Is this supported in the latest version of ESLint?

[ungoldman]

Seems like it should: eslint/eslint#9957
