I think it is self explanatory but if you need to talk about the code just tell me :)

Yes Dieg! I need a little more explanation. I understand the code up to .split("featuring")[0], but what does .trim() do? Thank you

I will take advantage of this question and recommend you the official documentation of MDN to search about Js implementations :)

The trim erases the blanks at the start and the end of the string, in this case, as we splitted it by "featuring", your [0] can have an space at the end and maybe make fail your test, if you had, this is the reason of the removal :)
