Uses typedArray's internal [[ArrayLength]]
info: |
22.2.3.23.2 %TypedArray%.prototype.set(typedArray [ , offset ] )
1. Assert: typedArray has a [[TypedArrayName]] internal slot. If it does not,
the definition in 22.2.3.23.1 applies.
...
20. Let srcLength be the value of typedArray's [[ArrayLength]] internal slot.
...
22. If srcLength + targetOffset > targetLength, throw a RangeError exception.
