Code failing at Convert Strings to URL Slugs

JavaScript
1

Hi all!

My code in this challenge is failing and I don’t understand why. It returns * The globalTitle variable should not change.* and it is not changing, as you can check in the console.log. Any clue of what is going on? Might it be a bug?


// the global variable
var globalTitle = "     Winter Is  Coming";
// Add your code below this line
function urlSlug(title) {
  let url = title.trim().toLowerCase().split(/\s+/).join("-");
  console.log(title);
  console.log(url);
}
// Add your code above this line

var winterComing = urlSlug(globalTitle); // Should be "winter-is-coming"

It’s because you literally changed globalTitle’s value.

If you reset your code, it won’t complain anymore. Here is what it looks like by default.

var globalTitle = “Winter Is Coming”;
