These are valid points (though you can reduce an empty array provided
you specify the "identity").  But I wonder if you feel the same about:

  > [].every(x=>x)
  true
  > [].some(x=>x)
  false

And would you object to [].sum() being 0 and [].product being 1?  (I
know ECMAScript has neither, I'm just interested in how you see similar
situations.)

I was with you up to this point.  The infinity is not pulled out of
nowhere -- there's a reason for it, even if you don't think it's a good
one (or a good enough one).  And even if you disagree with the choice,
it's certainly not a hack, and defending it is no reason be barred from
working with JavaScript.
