| 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. |
