I've used join too (though not with an empty separator, indeed), and
map/filter for various string pack and encode operations, but I don't
think that I would mind too much having to say

Array.join(strOrDataThing, "\n");

instead of

strOrData.filter(function (v) { return v.charCodeAt(0) < 128; });
