bug with: The globalTitle variable should not change.

In the exercise, one of the condition is “The globalTitle variable should not change.” but it returns an error if you modified the var (for debugging) at the top, even if your function doesn’t mutate it. The verification should be that the initial globalTitle variable is the same as the final one, instead of simply looking to match it to a string.

// The global variable
var globalTitle = " Winter Is  Coming";

// Only change code below this line
function urlSlug(title) {
  return title
    .toLowerCase()
    .trim()
    .split(/\s+/)
    .join("-");
};
// Only change code above this line
console.log(globalTitle);
urlSlug(globalTitle);
console.log(globalTitle);

I should not have used the word “mutable”. Looking at the challenge again, I think it would be fine to remove the global variable all together as it is not used in any other test (except the first). So, my suggestion is to remove the globalTitle declaration and remove the first test, unless someone else can find a good reason to keep them.

By all means, go ahead! 🙂
