What's the difference between using the Return value and just letting the code finish?

231,268 PointsIf you use a plain "return;", there's no difference from just hitting the end of the function.
But if you use it to return a value (like "return someValue;") it sends that value back to the point of the program that called the function, where just hitting the end does not.

231,268 PointsWhen the function ends, either by reaching the closing brace or from a "return", the program continues from the point where the function was called.
