javascript - 获取对象属性的最大值

Question

我正在尝试获取对象中所有wins属性的最大值。这是该对象的一个​​简短示例，我试图获取该对象的 Wins 属性的最大值，即 11。

var coach_wins = {
  "player1": [
    {
      year: 2015,
      wins: 6
    },
    {
      year: 2016,
      wins: 6
    }
  ],
  "player2": [
    {
      year: 2015,
      wins: 11
    },
    {
      year: 2016,
      wins: 6
    }
  ]
};

目前我正在计算对象的长度，然后使用 for 循环遍历对象并获取键:

coach_wins[Object.keys(coach_wins)[i]];

然后再次执行此操作并存储每个获胜值的值；

有没有更有效的方法？

谢谢。

var coach_wins = {
  "player1": [
    {
      year: 2015,
      wins: 6
    },
    {
      year: 2016,
      wins: 6
    }
  ],
  "player2": [
    {
      year: 2015,
      wins: 11
    },
    {
      year: 2016,
      wins: 6
    }
  ]
};

var max = Object.values(coach_wins) //get all the values of the object
  .reduce(function(largest, player){ //reduce the max for all player
    return player.reduce(function(largest, record){ //reduce the max for each player
      return (largest > record.wins ? largest : record.wins);
    }, largest);
  }, 0);

console.log(max);
