Im wondering why we are still using var instead of const & let this late into this course? Is there a purpose for this?

I am just wondering because I thought at this point we should not be using var at all. I ask just because when it comes to employers Id imagine they ask the same thing.

It's due to the age of the course. Unfortunately, Treehouse doesn't provide time stamps when releasing courses. I quickly checked one of the older Questions and it was dated to June 2016. ES2015 courses didn't start to come out until just after this time period. Also, courses take time to create. Official release and production dates can be many months in between. Var is far from dead, by the way. Kyle Simpson and many other top JS evangelists still use and recommend it.
