return function, try writing a few functions yourself to get them to return some values. You can put anything that can be placed on the right side as the return value of a function. The end of the script is a puzzle. I use the return value of a function as a parameter to another function. I link them together, just like I write math equations. It may be a bit hard to read, but you'll know the result if you run it. Next, you need to try to make t
