We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, it's part of your grades and it wouldn't be at all fair for us to do it all for you.
So start here, and see if you can work out what to write for your tutor:

JavaScript Array find() Method[
^]
JavaScript Array from() Method[
^]
JavaScript Array map() Method[
^]
If you can't work it out from there, use
JSFiddle[
^] to play with them until you do understand.
