description: >
Use prototype from new target if it's an Object
info: |
22.2.4.5 TypedArray ( buffer [ , byteOffset [ , length ] ] )
This description applies only if the TypedArray function is called with at
least one argument and the Type of the first argument is Object and that
object has an [[ArrayBufferData]] internal slot.
...
4. Let O be ? AllocateTypedArray(constructorName, NewTarget,
%TypedArrayPrototype%).
...
22.2.4.2.1 Runtime Semantics: AllocateTypedArray (constructorName, newTarget,
defaultProto [ , length ])
1. Let proto be ? GetPrototypeFromConstructor(newTarget, defaultProto).
2. Let obj be IntegerIndexedObjectCreate (proto, «[[ViewedArrayBuffer]],
[[TypedArrayName]], [[ByteLength]], [[ByteOffset]], [[ArrayLength]]» ).
...
9.4.5.7 IntegerIndexedObjectCreate (prototype, internalSlotsList)
...
10. Set the [[Prototype]] internal slot of A to prototype.
...
12. Return A.
