Python Development Techdegree Graduate 35,350 PointsHi Herman! I know it's been 2 weeks, but here's something if you haven't found an answer yet.
I had the same question and saw yours. I found this article while looking for an answer. To summarize, setInterval() returns an intervalID every time it runs. You can use that ID to pass into other functions that will interact with that particular interval such as clearInterval() which will stop the interval whose ID is passed into it.
^^That code will console.log an incrementing number every second, and will stop once it reaches 10. The way it was stopped was by using the intervalID that setInterval() created and passing it into the clearInterval() function. If this is still confusing the article does a much better job at explaining it than I haha.
