function urlSlug(title) {   
  let str =  ''.concat(title)
  .split(/\W/)
  .filter(a =>  a !== '')
  .join("-")
  .toLowerCase();

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

You need the globalTitle to be as it was in the original code - remove the space at the beginning

I have try this solution from hints

function urlSlug(title) {   
  return title
  .split(/\W/)
  .filter(a =>  a !== '')
  .join("-")
  .toLowerCase(); 
 
}

I have try this solution

function urlSlug(title) {
  return title
  .toLowerCase()
  .trim()
  .split(/\s+/)
  .join('-');
}

Because you don’t read the hints:

REMOVE the space in globalTitle before the W.
