Intl.supportedValuesOf ( key )
18 ECMAScript Standard Built-in Objects:
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 }.
