Should there be a break keyword after each case for both switch statements?

In this case however break statements are unnecessary since once a condition is met we return the value and no other lines of code will be executed regardless.

8,534 PointsBen didn't forget. Break is an important statement because without it would "invade" all the other case conditions. Anyway breaks not only were not important in that case, but were totally uses. Why? Because there was a return statement, which is much stronger than a break since it closes basically the function's runtime in that line. Basically it's like "enough here, return this value and do nothing more"
