javascript - 如何组合对象数组中的每个值？

Question

我目前正在做一个简单的掷骰子应用程序，我有以下对象:

die = [
  {
    ofWhat: 6,
    score: [6]
  },
  {
    ofWhat: 6,
    score: [1] 
  },
  {
    ofWhat: 6,
    score: [5] 
  }
]

我想获取每个分数并将它们组合成一个值，以便我可以看到该数组中每个分数的总和。

像这样:6+1+5

我怎样才能实现这个目标？

我尝试过的:

total = 0;

this.die.forEach((die) => {
  die.score.forEach((score) => {
    this.total += score;
  });
});

我得到 NaN

编辑:我在对象中犯了一个错误

die = [
  {
    ofWhat: 6,
    score: [6]
  },
  {
    ofWhat: 6,
    score: [1] 
  },
  {
    ofWhat: 6,
    score: [5] 
  }
]

total = 0;

this.die.forEach((die) => {
  die.score.forEach((score) => {
    this.total += score;
  });
});

console.log(total)

试试这个

        let die = [
          {
            ofWhat: 6,
            score: [6]
          },
          {
            ofWhat: 6,
            score: [1] 
          },
          {
            ofWhat: 6,
            score: [5] 
          }
        ];
        let sum = 0;
        die.forEach(i => {
            i.score.forEach(val => {
                sum += val;
            });
        });
        console.log(sum);
