Parameter buffer: An Array Buffer object that should be used as the backing store for the created JavaScript Typed Array object.

Parameter exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.

Returns: A JSObjectRef that is a Typed Array or NULL if there was an error. The backing store of the Typed Array will be buffer.
