从对象数组中删除原始对象和重复对象 - JS

const arr = [{
    title: "sky",
    artist: "Jon",
    id: 1
  },
  {
    title: "rain",
    artist: "Paul",
    id: 2
  },
  {
    title: "sky",
    artist: "Jon",
    id: 1
  }
];
const uniqueScenarios = Array.from(new Set(arr.map(a => a.id)))
  .map(id => {
    return arr.find(a => a.id === id)
  })

console.log(uniqueScenarios)

const arr1 = [{
    title: "sky",
    artist: "Jon",
    id: 1
  },
  {
    title: "rain",
    artist: "Paul",
    id: 2
  },
  {
    title: "sky",
    artist: "Jon",
    id: 1
  },
  {
    title: "rain",
    artist: "Paul",
    id: 2
  }
];
const uniqueScenarios1 = Array.from(new Set(arr1.map(a => a.id)))
  .map(id => {
    return arr1.find(a => a.id === id)
  })

console.log(uniqueScenarios1)

const
    array = [{ title: "sky", artist: "Jon", id: 1 }, { title: "rain", artist: "Paul", id: 2 }, { title: "sky", artist: "Jon", id: 1 }, { title: "rain", artist: "Paul", id: 2 }],
    ids = array.reduce((r, { id }) => (r[id] = !(id in r), r), {}),
    result = array.filter(({ id }) => ids[id]);

console.log(result);
