+description: Array.fromAsync meets the requirements for built-in objects
+info: |
+  Unless specified otherwise, a built-in object that is callable as a function
+  is a built-in function object with the characteristics described in 10.3.
+  Unless specified otherwise, the [[Extensible]] internal slot of a built-in
+  object initially has the value *true*.
+
+  Unless otherwise specified every built-in function and every built-in
+  constructor has the Function prototype object, which is the initial value of
+  the expression Function.prototype (20.2.3), as the value of its [[Prototype]]
+  internal slot.
+
+  Built-in functions that are not constructors do not have a "prototype"
+  property unless otherwise specified in the description of a particular
+  function.
