Functions- Review

Over the past few lessons, we have learned how to declare and call functions, how to write helper functions, and how to refactor our function syntax to make our code more readable. If you need to review, work through the lessons again or ping a tutor for help. When you’re ready, move on to the next set of lessons where we will be discussing scope.
