Map() method is unacceptable

Tell us what’s happening:

I got the same output using map() method, but the validator doesn’t accept it. Why is this happening?

Your code so far

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

// Only change code below this line
function urlSlug(title) {

return title.split(/\W/).map(word => word.toLowerCase()).join("-")

// Only change code above this line

Take a closer look at the specific case that is not passing. Try:

console.log(urlSlug(" Winter Is   Coming"));

Got it. Changed map to filter. It works. Thank you!
