  Link broke with new commit, here's a stable one: https://github.com/jstimpfle/tetris-on-a-plane/blob/d5d4d821aed95d9f1618f410ddca3b6b8b2c8853/tetris.js#L101 https://github.com/jstimpfle/tetris-on-a-plane/blob/d5d4d821... This is a test to see how quickly someone brings up the stackoverflow link ;-)

    In other words, it's a crappy way to write `i-- > 0` Note that it's not logically equivalent to `for (var i = 5; i > 0; i--)` because in this case the `i--` operation is applied after the body of the loop. Try it in your browser: for (var i = 5; i-- > 0;) { console.log(i); } //4,3,2,1 for (var i = 5; i > 0; i--) { console.log(i); } //5,4,3,2,1

      This is why I actually like this syntax (and get fun out of provoking "shudder" comments). - Can use the same limits as in ascending iteration - Can do decrementing in for loop (no extra line) - The arrow unambiguously signals that the iteration is correct :-)

  "Clever" code. shudder It's confusing to read for anybody not used to it, particularly as you need to set the "initial" value to the "actual initial value"+1.
