description: Default [[Prototype]] value derived from realm of the NewTarget.
|
|
info: |
|
|
Intl.Segmenter ([ locales [ , options ]])
|
|
1. If NewTarget is undefined, throw a TypeError exception.
|
|
3. Let segmenter be ? OrdinaryCreateFromConstructor(NewTarget, "%Segmenter.prototype%", internalSlotsList).
|
|
...
|
|
15. Return segmenter.
|
|
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.
