Imprecise.

String comparison *can* be the default for Array.prototype.sort(); in fact, 
if the /comparefn/ argument is “undefined” (including not specified), the 
sort order is *implementation-dependent*.  Implementations need not agree on 
a default comparator.

So specifying a comparator is *required* in *portable* code *regardless* of 
the type of the elements (which can be of a different type each; but see 
Typed Arrays).
