let vs var

I used let for this practice assignment.

Everything worked fine, but I saw that they used var in the video.

Does it matter?

In nearly all situations you will encounter in beginner through intermediate exercises, there won't be any practical difference between using let and var for declarations. The differences are mainly related to scope and hoisting.

For the technical details, see these MDN pages on let and var.
