Tell us what’s happening:
Hello everyone!
I wrote this solution to end the challenge, the problem is that it creates a dash also on the last word and, when it finds a phrase with a space, it inserts two dashes instead of one. Can you explain and make me understand how to solve and where am I wrong?
Thank you
Your code so far
// the global variable
var globalTitle = " Winter Is Coming";
// Add your code below this line
function urlSlug(title) {
let newStr;
newStr = title.toLowerCase()
.trim()
.split(' ')
.map((el, index) => el + '-')
.join('');
console.log(newStr);
}
// Add your code above this line
var winterComing = urlSlug(globalTitle); // Should be "winter-is-coming"
