Our first event
All the functions we worked with so far were functions that we triggered. If the Internet was linear that would do, but a computer application has a lot of events that are not linear and we don't know when they'll happened. For example, when a user clicks on something or when the page loads. In this lecture, we're going to take our first peek at a different type of function which is called a callback or an event. The first event we are going to look at is the onload event which triggers whenever the page is loaded.
