The reality is that most new devs that are learning JavaScript for the first time are going to be more aware of let and const, but may have never had a formal introduction or understand why it is this way (especially when reading documents and old tutorials). For many devs that used JavaScript early in their careers and are coming back, looking at the ES2015 changes can be very confusing.

The primary difference with var, let, and const comes when either re-declaring or updating them.
