Intl.DisplayNames ([ locales [ , options ]])
1. If NewTarget is undefined, throw a TypeError exception.
2. Let displayNames be ? OrdinaryCreateFromConstructor(NewTarget, "%DisplayNamesPrototype%",
« [[InitializedDisplayNames]], [[Locale]], [[Style]], [[Type]], [[Fallback]], [[Fields]] »).
3. Let requestedLocales be ? CanonicalizeLocaleList(locales).
...
CanonicalizeLocaleList ( locales )
1. If locales is undefined, then
a. Return a new empty List.
2. Let seen be a new empty List.
3. If Type(locales) is String, then
a. Let O be CreateArrayFromList(« locales »).
4. Else,
a. Let O be ? ToObject(locales).
5. Let len be ? ToLength(? Get(O, "length")).
ToLength ( argument )
1. Let len be ? ToInteger(argument).
