Apply Functional Programming to Convert Strings to URL Slugs78

** what’s wrong in it?

Your code so far

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

// Add your code below this line
function urlSlug(title) {
    var t=title.trim().split(/\W+/);
   // console.log(t);
  return t.join("-").toLowerCase();
// Add your code above this line

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