  22.2.3.26 %TypedArray%.prototype.sort ( comparefn )

  When the TypedArray SortCompare abstract operation is called with two
  arguments x and y, the following steps are taken:

  ...

  NOTE: Because NaN always compares greater than any other value, NaN property
  values always sort to the end of the result when comparefn is not provided.
