I think my code looks pretty good but open to suggestions.

It looks great! You're definitely getting "in the groove".

One small improvement you can make is skipping the creation of an intermediate variable if the only use for it is to return the result of a calculation. Instead, you can return the calculation directly. For example:

function rectangleArea (width, height) {
  return width * height;
}

And you might not see this until later courses, but there's also a newer function definition syntax you can use that makes it a bit more compact yet:

const rectangleArea = (width, height) => width * height;

Thanks for the feedback! There seems to always be a way to shorten how much code you need to write to get the same results.
