shortcut prod.inventory instead of product.inventory works

How is it possible that we can use prod.inventory? Javascript automatically find what we trying to access just by passing shortcut prod.inventory instead of product.inventory as long as we have only one inventory in the whole code?

thank you for answer

The term "prod" is a function parameter. It doesn't represent "product" until the function is called and that is passed as the first argument in the call. And that reference is only valid inside the function.

You could have many other items in the code, but anytime the function is called one of them would need to be named as the argument. Then that other one would be accessed inside the function code as "prod".
