In this video we're going to talk about objects and functions. …And how objects are passed by reference into functions. …And we're going to talk about what that means. …So to start off, let's look at this object. …It's called Calvin. And it has this form. …Its name is Calvin, its best friend is Hobbes, and its form is human boy. …Now along with this object I have a function I've, which is the transmogrifier. …And what this does is it takes a Calvin and transforms its form into something else. …Let's take a look at the definition of this function.…
So here it is. It accepts a Calvin object. …And then we do a little bit of type checking to make sure that the argument …is at least something like what we expect it to be. …When you're writing functions, it's a good idea to make sure that the input …that you're accepting into the function is of a structure that you expect. …Otherwise your code later could break down and you'd have a lot of debugging to do. …This is especially important if you're writing a function that could accept …
