description: Promise.resolve `length` property
info: >
ES6 Section 17:
Every built-in Function object, including constructors, has a length
property whose value is an integer. Unless otherwise specified, this value
is equal to the largest number of named arguments shown in the subclause
headings for the function description, including optional parameters.
[...]
Unless otherwise specified, the length property of a built-in Function
object has the attributes { [[Writable]]: false, [[Enumerable]]: false,
[[Configurable]]: true }.
includes: [propertyHelper.js]
