You're correct. Please, however, use a spoiler tag when sharing code that could lead people to the solution.

use the spoiler flag if discussing code / methods. i have added the flag to your comment

explain why it works)

Can someone clarify something for me?
I did the exact same solution, but wrapped in a if-else statement to verify the true and false returns.

but will the return always be true or false? So no need to wrap in if-else?
Thanks

Very nice and clean. I got very close with my attempt. Cheers from Brazil

Nice

Thank you! :)

Agree, need more tests

Indeed. Please add test cases and a more detailed description. Are you actually passing in multiple arrays or a single array? Where is the function parameter? How do we handle duplicate names?
