Why it's returning global Title should not be changed

JavaScript

Tell us what’s happening:

Your code so far


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

// Add your code below this line
function urlSlug(title) {
  let str = title;
  return str.trim().split(/\s+/).map((e) => e.toLowerCase()).join('-');
  
}
// Add your code above this line

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

Because you changed this text and added more spaces.

Reset your code, don’t touch this line and try again.
