Get properties from array of objects group by objects

Question

Good day, I have an array artists[] of Proxy-objects. Proxy by themself also are arrays of objects (as I understood). Each of inner objects has property "artistName" (photo). Meanwhile third Proxy has two.

I need to get smth like this:

[
  ["Queen"],
  ["Pink Floyd"],
  ["Elvis Presley", "Pink Floyd"],
]

So, as result we get arrays of artist's names grouped by Proxy objects. Please, help!

Post the original array.

There are two levels of arrays, so you'll need two loops (or map functions). Give this a try

const names = artists.map(grp => grp.map(band => band.artistName))
