Hey Rodi, as you learn more about JavaScript you'll find that console.log has many uses for helping programmers to keep track of what is going on in their code. It is a useful place for someone working with the code to see what is going on "behind the scenes" without displaying the content on the webpage itself. In addition, console.log is often used for debugging code since it allows you to see exactly which parts of your code are running correctly, and which are not.

You can use the console.log, to show that the program has "started" and "finished" so that you know there was nothing that was missed because the program made it to the last line! It's an awesome way to make sure everything ran!

You can also use console.log in mathematical operations to help you build bigger applications.
