    If your data is a field like languages, you could use $languages.map(obj => obj.language) to pull just those values out.

    Hello tbranco,

    Thanks a lot, that's awesome! I'll share this with my team so that we can all learn.

    Just one thing however... The reduce() method seems to work, but it's also returning an error message:

    Is this just a typo, or we can safely ignore the message?

    Kind regards,

    JF
