Apply Functional Programming to Convert Strings to URL Slugs "front space issue"

Tell us what’s happening:

almost through but i cant do away with the front starting whitespace

Your code so far


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

// Add your code below this line
function urlSlug(title) {
 return title.toLocaleLowerCase().split(/\s/).join("-");

}
// Add your code above this line

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

you can try the trim method
https://www.w3schools.com/jsref/jsref_trim_string.asp

or you can manually do the same thing by matching everything that isn’t a space at the beginning
then matching everything that isn’t a space at the end
leaving a trimmed sentence.

thank you solved the problem already using filter() method
