So, the problem with scripting modern day websites is many of them use asynchronous techniques, like Ajax, to load their webpages. This method allows web servers to update parts of their webpage without reloading the entire thing. Because of this they're able to create fast loading and dynamic webpages. However, this becomes a problem when our Selenium web driver tries to locate a web element before it's loaded. This will raise an exception with our script and our program will not work. And this transitions us into why we need wait functions.
