Now, when we have an environment that has a value for each of the free variables, we say that we've closed the function. And, when we take the function and the environment together, we say we have a closure.

Window is the global object. It may seem a little weird, but the window object acts as your global environment, so the names of any properties or methods from window are resolved even if you don't prepend them with window.
