QUESTION
How does counting instances of a callback function work in node.js?
I was working on the 9th exercise of learnyounode (below the official solution). As I understand it, the httpGet function is called three times, running through process.argv[2], [3] and [4]. But how could count ever === 3? Don't the individual functions just get to one? How does one call of httpGet know of the other ones?

var
is defined in the global scope so it’s value updated between calls
