Re^3: Is it safe to append to the array you are iterating overby BrowserUk (Pope)

The problem is that even if the logic in the loop body doesn't cause an infinite loop; you are at the very least also iterating over all the additional elements that you push for no good reason. You've just pushed those values; you presumably don't want them to cause further pushes.
Why do pointless extra work when it is so easily avoided?
