You can't declare a "const" without assigning a value at the same time, since you will not be allowed to assign one later.

But another issue is the challenges in this course don't accept ES6 syntax. So while it would be legal to use "let", that is also not allowed here. I'm sure this will change when the course is refreshed but for now just stick to ES5 syntax.
