In this function, i is declared (var i = 0), incremented (by the i++),
and then compared with len.

I can't see why i would ever have a value other than 1 when this
statement:

  if (i >= len) return; // no more changing

is executed. The same is true of your function. So what is the point of
the variable i or indeed the test to compare with len ??
