Question

Cappuccino defines a _UID property for every instance of objects it creates, but is this used for anything?

Was it helpful?

Solution

It's used in dozens of places, which you could see by doing something like "git grep UID" on the source code. Most often it is used as a hash key. Also, it's spelled "Cappuccino."
