I have a reference to an annonymous array, which I am looping through with

Based on certain criteria, I want to add a new item to the end of the

Nope; as your intuition suggested, it's bad to modify the variable
while looping over it.
If not, what would be a better solution?
Perhaps collect any new elements into another array, then push them
onto the main array after the loop ends. But maybe there's a way to
rethink your algorithm, especially if you want to re-check the new
elements. (Maybe one array of unchecked items, and another array of
ones that are already checked?)
Hope this helps!
