Should we be using "let" and "const" now instead of "var"? What will be accepted in this curriculum?

In most cases where scope is not an issue, you can use "var"; but it would be good practice to use "const" whenever you can (when the value will not be changed) and "let" otherwise.

I undestand that this material was prepared before let and const came out, however you could at least set the interpreter to understand let and const. I get syntaxError if I use them

I understand your point and I agree with you, however, on the other side, It's good to learn JS from scratch, step by step.
