229,644 PointsA setter method typically does not return anything; so if the return value is tested (as is automatically done by the console), it is normal for it to show "undefined".
A corresponding getter method isn't technically necessary for the setter to work, but is usually necessary for the program that called the setter to retrieve the established value at a later time.
