kosamari / TowArrayPrint.js

	/*
	What is the optimal way to print values of 2 arrays alternately? (every 5 sec)
	* Items in both arrays could change at any given moment
	* update to each array needs to be applied imminently
	* if array is empty, it will not print any value (and move to the other array)

	So if you start with following arrays
	var arr0 = ['1','2','3']
	var arr1 = ['a','b','c']
	It would start printing
