description: Boolean littleEndian argument coerced in ToBoolean
esid: sec-dataview.prototype.getbigint64
info: |
  DataView.prototype.getBigInt64 ( byteOffset [ , littleEndian ] )

  1. Let v be the this value.
  2. If littleEndian is not present, let littleEndian be undefined.
  3. Return ? GetViewValue(v, byteOffset, littleEndian, "Int64").

  24.3.1.1 GetViewValue ( view, requestIndex, isLittleEndian, type )

  ...
  5. Set isLittleEndian to ToBoolean(isLittleEndian).
  ...
  12. Let bufferIndex be getIndex + viewOffset.
  13. Return GetValueFromBuffer(buffer, bufferIndex, type, false,
  "Unordered", isLittleEndian).

  24.1.1.6 GetValueFromBuffer ( arrayBuffer, byteIndex, type,
  isTypedArray, order [ , isLittleEndian ] )

  ...
  9. Return RawBytesToNumber(type, rawValue, isLittleEndian).

  24.1.1.5 RawBytesToNumber( type, rawBytes, isLittleEndian )

  ...
  2. If isLittleEndian is false, reverse the order of the elements of rawBytes.
  ...
