I think the readability to an inexperienced coder greatly improves just by moving the "robot.number++" outside the conditional and perhaps even changing it to "robot.number = robot.number + 1" Though that is slightly different (since ++ will execute after the conditional is evaluated when following the lval but the change will make it run before) Edit: on 2 seconds though... put that code AFTER the if statement and it would behave exactly as the example.
