I think Alexey is also asking for a way to create typed arrays.

> JSGetTypedArrayBase(JSValueRef) -> returns void* of the first element in the view or the base of the buffer
> JSGetTypedArrayByteLength(JSValueRef) -> returns size_t of the number of bytes that the view sees or the byteLength of the buffer.

This would be 

JSObjectGetTypedArrayBase(JSContextRef, JSValueRef)
JSObjectGetTypedArrayByteLength(JSContextRef, JSValueRef)

Maybe "BytesPtr" is a better name than "Base", to match our string and data APIs.

How would I know the data type in the typed array? How long would the returned pointer remain valid? What happens after neutering?
