6 description: Default [[Prototype]] value derived from realm of the NewTarget.
8 NativeError ( message )
10 1. If NewTarget is undefined, let newTarget be the active function object; else let newTarget be NewTarget.
11 2. Let O be ? OrdinaryCreateFromConstructor(newTarget, "%NativeErrorPrototype%", « [[ErrorData]] »).
15 OrdinaryCreateFromConstructor ( constructor, intrinsicDefaultProto [ , internalSlotsList ] )
18 2. Let proto be ? GetPrototypeFromConstructor(constructor, intrinsicDefaultProto).
19 3. Return ObjectCreate(proto, internalSlotsList).
21 GetPrototypeFromConstructor ( constructor, intrinsicDefaultProto )
24 3. Let proto be ? Get(constructor, 'prototype').
25 4. If Type(proto) is not Object, then
26 a. Let realm be ? GetFunctionRealm(constructor).
27 b. Set proto to realm's intrinsic object named intrinsicDefaultProto.
