[NaNaN]

I think all these bytes are not creative. !![]+2+2 ? !''|2+2 ? 1|2+2 ? Why the use of new operators? Why not just write 1+2+2 ?

Well if you made a general add function that always performed an or operation on the least significant bit, it would be pretty interesting. You'd always flip odd and even in any addition.

To make many more examples of why Javascript is not a language for beginners.

  var tens = ['10','10','10','10','10','10','10','10'].map(parseInt);
  var ten = tens[tens.length-1];
  var two = ten % 4;
  console.log(two + 2);
