My code works, but I don't understand why. Can someone help me understand this statement from the lesson: "We see i starts off at value 0. The for loop runs until i < 4." I'm confused because 0 is ALREADY less than 4, so the stop condition seems like it's already met when the first loop runs, and therefore shouldn't run at all. It seems like the stop condition should be i > cities.length. What am I failing to understand? Thanks in advance.
