Hey Carlos,

You're one the right track, but there are a couple of things.

  1. You aren't escaping the backslash in the regular expression. You want the backslash, so it needs to be escaped so the compiler knows to use it (essentially just add another one to escape the first one (//).
  2. Challenges are often not exactly as what you learned in the video. Videos offer the basic explanations, and the challenges usually want you to take that and apply it to a different set circumstances. In the Video, you learned how to negate a regular expression, but the challenge does not ask for this. In the challenge, you actually are wanting to split on whitespace, not the opposite. So, you cannot have the square brackets (or the carat, which isn't there anyways) in the regular expression.

With all that in mind, your code is mostly correct in syntax, it is just not what that challenge is asking for.

Give it another go after fixing up those two small errors (add the escape character and deleted the brackets), and you should be good to go.

Keep Coding! :) :dizzy:
