description: >
The returned "unit" values are sorted, unique, and well-formed.
info: |
Intl.supportedValuesOf ( key )
1. Let key be ? ToString(key).
...
7. Else if key is "unit", then
a. Let list be ! AvailableUnits( ).
...
9. Return ! CreateArrayFromList( list ).
AvailableUnits ( )
The AvailableUnits abstract operation returns a List, ordered as if an Array
of the same values had been sorted using %Array.prototype.sort% using
undefined as comparefn, that contains the unique values of simple unit
identifiers listed in every row of Table 1, except the header row.
includes: [compareArray.js, testIntl.js]
features: [Intl-enumeration, Array.prototype.includes]
