Hello Khan Academy, When I started this video, The first thing I heard is "Now that you have mastered the basics of functions...". But on the Into to JS playlist, functions comes next after this video. How do I watch the videos in this playlist in the right order?

I feel like this idea is easy to understand and only made complicated by the strange decision making shown with variables. Global variables seem ideal for most cases, especially if the same trait will be factored into multiple functions. Local variables seem only useful for receiving information and returning an answer as well as formatting the usage of operations within a function.
