Trouble with converting to url slugs challenge

I tried my best to make it work but for some reason the .trim doesn’t shave off the first extra space. If anyone has some advice or a tip please let me know. Thanks!

Your code so far

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

let slu = title.trim().toLowerCase().split(' ').join('-');

return slu;

// Only change code above this line

Challenge: Apply Functional Programming to Convert Strings to URL Slugs

Link to the challenge:

The problem isn’t the first space:

function urlSlug(title) {
  let slu = title
    .split(' ')
  return slu;

console.log(urlSlug(" Winter Is  Coming")); // winter-is--coming

Ohhhhhh, ok thanks a bucket LOL :laughing:

I hadn’t run a console.log so I should probably start doing that more often

What would you recommend I try? I feel like .filter or REGEX is my best option.

Since you’ve got a pretty good functional approach going, I’d go with ‘filter’. The callback function actually ends up being really straightforward once you see what it is :slight_smile:

Ok thanks, Imma take a break from this to get some of my other tasks done but hopefully I’ll come back later tonight with some fresh eyes :grinning_face_with_smiling_eyes:
