Creating a timer

Throughout this chapter we haven't done any animations. We were too busy exploring objects and the Date object specifically. In this last lesson of this chapter we're going back into animation as we create a timer. We will be using the functions setInterval and with it, we will update our screen once a second. By the end of this lesson, you will know how to create content that updates on a timely base. The main functions we are going to explore are: setInterval and clearInterval.
