description: Default [[Prototype]] value derived from realm of the NewTarget.

info: |

Intl.DateTimeFormat ( [ locales [ , options ] ] )

|
|
1. If NewTarget is undefined, let newTarget be the active function object, else let newTarget be NewTarget.
|
|
2. Let dateTimeFormat be ? OrdinaryCreateFromConstructor(newTarget, "%DateTimeFormatPrototype%", « ... »).
|
|
...
|
|
6. Return dateTimeFormat.

|
|
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.
