  24.2.4.12 DataView.prototype.getUint32 ( 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, "Uint32").

  24.2.1.1 GetViewValue ( view, requestIndex, isLittleEndian, type )

  ...
  6. Let buffer be view.[[ViewedArrayBuffer]].
  7. If IsDetachedBuffer(buffer) is true, throw a TypeError exception.
  ...
  11. If getIndex + elementSize > viewSize, throw a RangeError exception.
