}
It doubles the array in each iteration, so it can create a really large array with few iterations.

How can I compare two lists in python and return matches
...>>> b = [9, 8, 7, 6, 5]
>>> set(a) & set(b)
{5}
if order is significant you can do it with list comprehensions like this:
>>> [i for i, j in zip(a, b) if i == j]
[5]
(only works for equal-sized lists, which order-significance implies).

What is Ember RunLoop and how does it work?
