esid: sec-intl.pluralrules
description: Default [[Prototype]] value derived from realm of the NewTarget.
info: |
Intl.PluralRules ( [ locales [ , options ] ] )
1. If NewTarget is undefined, throw a TypeError exception.
2. Let pluralRules be ? OrdinaryCreateFromConstructor(newTarget, "%PluralRulesPrototype%", « ... »).
3. Return ? InitializePluralRules(pluralRules, locales, options).
OrdinaryCreateFromConstructor ( constructor, intrinsicDefaultProto [ , internalSlotsList ] )
...
2. Let proto be ? GetPrototypeFromConstructor(constructor, intrinsicDefaultProto).
3. Return ObjectCreate(proto, internalSlotsList).
GetPrototypeFromConstructor ( constructor, intrinsicDefaultProto )
...
3. Let proto be ? Get(constructor, 'prototype').
4. If Type(proto) is not Object, then
a. Let realm be ? GetFunctionRealm(constructor).
b. Set proto to realm's intrinsic object named intrinsicDefaultProto.
5. Return proto.
