Here are some of the standard tests for property metadata of the Array.fromAsync property and for the built-in function object. These don't require doing anything asynchronously, so can be considered separately from the Async Helpers RFC.

description: Value and property descriptor of Array.fromAsync.length
|
|
info: |
|
|
Every built-in function object, including constructors, has a *"length"*
|
|
property whose value is a non-negative integral Number. Unless otherwise
|
|
specified, this value is equal to the number of required parameters shown in
|
|
the subclause heading for the function description. Optional parameters and
|
|
rest parameters are not included in the parameter count.
|
|
|
|
Unless otherwise specified, the *"length"* property of a built-in function
|
|
object has the attributes { [[Writable]]: *false*, [[Enumerable]]: *false*,
|
|
[[Configurable]]: *true* }.
|
|
includes: [propertyHelper.js]
|

features: [Array.fromAsync]
