I think this course was created before ES2015 syntax was generally supported. Try using "var" instead of "let" for your declarations (as was done in the original code).

Also the final statement doesn't need to be enclosed in braces as it is unrelated to the "while". The "while" could have a semicolon after it (optional, but a "best practice").

I'm not going to bother with it it works so good enough for me :D
