Summary: Today, we will continue the function discussion and move to scope. First of all, I will discuss how to use callbacks. We will create couple of functions and pass a function as a parameter to another. We will see a different way of working with that when we pass an anonymous function. Then, I will start my discussion on scope. This is a very important concept because it is very easy to create bugs that are hard to find. We will see how to create variables on the global scope and ones in the function scope. We will continue this discussion in the next video.
