I think I incline towards adding support for let. But it doesn't have to be explicit or obvious, even in the test message. As long as we can keep that I am okay to update the tests.

It is looking for a specific solution that uses the var keyword.
"tests": [ "assert(code.match(/var.*?total\\s*=\\s*0.*?;/), 'message: <code>total</code> should be declared and initialized to 0');" ]

As a side note, a lot of the beginning javascript challenges force you to use var. I am pretty sure this is by design.

In many other begineer challenges I can use let or const without fail - I don't think users should be overly limited in how they can solve a challenge.

I think fcc should not only start supporting but also encourage using ES6 already. Furthermore, arrow functions also somehow buggy. I have encountered a problem while solving basic js tasks, where the same function written as an arrow function provides a different result than conventional function declaration. I have tested this on VScode and it was functioning normally.

Anyways too much off topic here. like I said it would be nice if fcc would already encourage using ES6 OR at least have a separate module to for teaching ES6 basics and new syntax.
