Do I understand it right?

once we created second array[] with return key we basically come back to the first array?

Is this what is Return for ?

If 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.

As the instructor says in the video, the return goes "just before the final closing brace". This puts it inside the function.

In fact, a return statement can only be used inside a function. Placing one outside of a function will cause an error.

Please could you explain me why we put "return" statement outside the function curly braces?
