Failing Convert Strings to URL Slugs

[DainiusMI]

I am failing to pass the test:
So my code bellow seemed to work until this test:

urlSlug(" Winter Is Coming") should return the string winter-is-coming .

and my browser dev tool console seems to output the result that the test asks for: winter-is-coming
This exercise hint section contains only solutions and I would like to solve it before checking them out.
So guidance would be appreciated…

Your code so far

// Only change code below this line
function urlSlug(title) {
return title.trim().toLowerCase().split(' ').join('-');
}
// Only change code above this line
urlSlug("A Mind Needs Books Like A Sword Needs A Whetstone");

When I put this at the bottom of your code:

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

I get this in the output:

winter-is--coming

That does not match the expected output.

Again thank you for your reply kevinSmith,
I am looking at the argument I pasted and got no clue where from did I copy it .
I have edited my split() function argument to fix the problem you have highlighted.
