description: >
  Uses target'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.
  2. Let target be the this value.
  ...
  10. Let targetLength be the value of target's [[ArrayLength]] internal slot.
  ...
  22. If srcLength + targetOffset > targetLength, throw a RangeError exception.
