+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* }.
