We are being taught to start a variable with "var", when every other source is telling us to switch to "let"? Is there an updated course available?

That’s a great question! You are right, most of the videos you watch will use let or const. And there are definitely some differences between them. I believe the reason you’re seeing var in some of the videos is simply due to the age of the recording. That being said, what you’re learning is still applicable.
If you’re just getting started with JavaScript, I wouldn’t stress over it too much. But if you want to dive deeper into the differences, here’s a very popular Stack Overflow thread on the topic. It’s a popular question!
Happy coding!
