231,261 PointsIf you are talking about the createDeck function, the first two arrays (suites and ranks) are used to build the third one (card). The "return" statement just ends the function and passes back the shuffled version of the 3rd array to the code that called it.
If that's not what you are asking about, please give more details and perhaps show the code in question.

returngoes "just before the final closing brace". This puts it inside the function.In fact, a
returnstatement can only be used inside a function. Placing one outside of a function will cause an error.
