如果您知道 arr 中对象的索引并且知道它不会更改，那么您可以使用index来获取对象然后对其进行解构

const { tier, rank, leaguePoints } = arr[1];
console.log(tier, rank, leaguePoints);

const arr = [
  {
    leagueId: "51f35167-0e62-41b0-bb5d-8ec376e754d7",
    queueType: "RANKED_FLEX_SR",
    tier: "GOLD",
    rank: "II",
    summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg",
    summonerName: "Impermanencë",
    leaguePoints: 1,
    wins: 7,
    losses: 5,
    veteran: false,
    inactive: false,
    freshBlood: false,
    hotStreak: false,
  },
  {
    leagueId: "0e4412d1-81c2-4839-9045-c0cb556ebdcb",
    queueType: "RANKED_SOLO_5x5",
    tier: "PLATINUM",
    rank: "III",
    summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg",
    summonerName: "Impermanencë",
    leaguePoints: 75,
    wins: 222,
    losses: 205,
    veteran: false,
    inactive: false,
    freshBlood: false,
    hotStreak: false,
  },
];

const { tier, rank, leaguePoints } = arr[1];
console.log(tier, rank, leaguePoints);

否则你需要使用find来获取元素然后解构。

const obj = arr.find((o) => o.queueType === "RANKED_SOLO_5x5");
const { tier, rank, leaguePoints } = obj;
console.log(tier, rank, leaguePoints);

const arr = [
  {
    leagueId: "51f35167-0e62-41b0-bb5d-8ec376e754d7",
    queueType: "RANKED_FLEX_SR",
    tier: "GOLD",
    rank: "II",
    summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg",
    summonerName: "Impermanencë",
    leaguePoints: 1,
    wins: 7,
    losses: 5,
    veteran: false,
    inactive: false,
    freshBlood: false,
    hotStreak: false,
  },
  {
    leagueId: "0e4412d1-81c2-4839-9045-c0cb556ebdcb",
    queueType: "RANKED_SOLO_5x5",
    tier: "PLATINUM",
    rank: "III",
    summonerId: "YZ9wH1Bldkndu5YnBb9cYn5corkcU_rDCVsVEaHDttelCVg",
    summonerName: "Impermanencë",
    leaguePoints: 75,
    wins: 222,
    losses: 205,
    veteran: false,
    inactive: false,
    freshBlood: false,
    hotStreak: false,
  },
];

const obj = arr.find((o) => o.queueType === "RANKED_SOLO_5x5");
const { tier, rank, leaguePoints } = obj;
console.log(tier, rank, leaguePoints);
