I don't understand the purpose of for in loops : <p>I've been working my way through the Javascript development track on Treehouse and am struggling with for in loops. I have been unable to locate any explanation of this loop in everyday language and am subsequently getting confused. What does for in actually do, and why would you use this loop as oppose to another loop? Is it basically just a way to assign a common label to each individual property of an object?</p>
