  24.2.4.9 DataView.prototype.getInt32 ( 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, "Int32").

  24.2.1.1 GetViewValue ( view, requestIndex, isLittleEndian, type )

  ...
  4. Let getIndex be ? ToIndex(requestIndex).
