The way I solved this did not require the return keyword and I would like clarifications as to why

// a function that calculates the area of a rectangle.
function calculateRectangle (width, height) {
    rectangleArea = width * height;
    console.log(rectangleArea);
}
calculateRectangle(5, 22);

Some functions do something, and some return something, and some may do both. This is an example of a function that doesn't return anything. Instead, it does something and displays the result directly on the console.

But let's say you were to call the function like this:

var answer = calculateRectangle(5, 22);

After that runs, the value of "answer" would be "undefined", because nothing was returned. But it would still display "110" on the console while it was running.
