javascript - 在不超过特定值的对象数组中找到最大值 - Javascript

Question

我有一个对象数组，想找到得分最高且不超过特定分数(例如 20 分)的玩家。我该怎么做？

    let playerScores = [ 
  { player: 'Dealer',
    score: 19,
    cards: 'A of ♥, 5 of ♦' },
  { player: 'Player1',
    score: 18,
    cards: '10 of ♦, 8 of ♦' },
  { player: 'Player2',
    score: 23,
    cards: '6 of ♦, 6 of ♥, J of ♠' }
    ]

console.log(playerScores)
// iterates through playerScores
for (let i in playerScores) {
    if (playerScores[i].score > 20) {
        console.log(playerScores[i].player + ' BUSTED!')
        // removes the object with a score over 21 from the array
        playerScores.splice(i,1)
    }
    return playerScores
}

Answer 1

可以先过滤数据，按分数排序，然后取第一个:

let filteredData = playerScores.filter(p=>p.score<=20).sort((a,b) => b.score-a.score);
let result = filteredData.length ? filteredData[0] : undefined;`
