  24.2.4.8 DataView.prototype.getInt16 ( byteOffset [ , littleEndian ] )

  1. Let v be the this value.
  2. If littleEndian is not present, let littleEndian be false.
  3. Return ? GetViewValue(v, byteOffset, littleEndian, "Int16").

  24.2.1.1 GetViewValue ( view, requestIndex, isLittleEndian, type )

  ...
  10. Let viewOffset be the value of view's [[ByteOffset]] internal slot.
  11. Let viewSize be the value of view's [[ByteLength]] internal slot.
  12. Let elementSize be the Number value of the Element Size value specified in
  Table 50 for Element Type type.
  13. If getIndex + elementSize > viewSize, throw a RangeError exception.
