If you know exactly the selector or object you are going to be running your function on 'this' isn't really as useful. What it does do is make our code more modular. Perhaps your function could operate on many different 'selectors'/different nodes. Using 'this' makes sure that we get the specific selector or object and can then make our changes to that object. So this allows us to generically refer to whatever selector or object that the function is being used on. "}}
