@Jorge

what seems more apparent is that the uncomfortable (to compile) integer++  is badly compile in JS and returns the wrong value, not the previous, or does the post-increment wrongly.  That would also justify that repetition of values between iterations.  Funnily it doesn't happy when the n++ is made out of any expression.

I find this bug really intriguing and way dangerous!
