What's the best way to filter unique values from an array of objects? for example from this array, [{value: 'a', label: 'A'}, {value: 'b', label: 'B'}, {value: 'a', label: 'C'}, {value: 'c', label: 'C'}], I want the unique objects comparing the value prop

This is what I've done so far

const houses = bonuses.map((bonus) => ({ value: bonus.bookie, label: bonus.bookie }))
  const uniqueHouses = Array.from(new Set(houses.map((bonus) => bonus.value))).map((bookie) =>
    bonuses.find((bonus) => bonus.bookie === bookie)
  )

const houses = bonuses.map((bonus) => ({ value: bonus.bookie, label: bonus.bookie }))
  const uniqueHouses = Array.from(new Set(houses.map((bonus) => bonus.value))).map((bookie) =>
    bonuses.find((bonus) => bonus.bookie === bookie)
  )

Which is the same as

const uniqueHouses = Array.from(
    new Set(
      bonuses
        .map((bonus) => ({ value: bonus.bookie, label: bonus.bookie }))
        .map((bonus) => bonus.value)
    )
  ).map((bookie) => bonuses.find((bonus) => bonus.bookie === bookie))

const uniqueHouses = Array.from(
    new Set(
      bonuses
        .map((bonus) => ({ value: bonus.bookie, label: bonus.bookie }))
        .map((bonus) => bonus.value)
    )
  ).map((bookie) => bonuses.find((bonus) => bonus.bookie === bookie))

!close nah man im dumb I need to rest This is what I wanted:

const houses = Array.from(new Set(bonuses.map((bonus) => bonus.bookie))).map((bookie) => ({
    value: bookie,
    label: bookie,
  }))

const houses = Array.from(new Set(bonuses.map((bonus) => bonus.bookie))).map((bookie) => ({
    value: bookie,
    label: bookie,
  }))
