I can’t figure out how to remove all whitespace from a string. I tried Googling, but I only get stuff showing how to do it using replace (the challenge says my should not use replace).
Any help is appreciated.
My code so far
// The global variable
var globalTitle = "Winter Is Coming";
// Only change code below this line
function urlSlug(title) {
return title.trim().toLowerCase().split(" ").join("-");
}
// Only change code above this line

you can also put a regex inside here, so that you can do it on any number of spaces
no, this doesn’t do what you want: filter will keep the elmenets in the array for which it returns a truthy value and and not keep for those of which it returns a falsy value. I don’t think trim is doing what you want there
