使用reduce不是可迭代对象Javascript对对象进行迭代时出错

如何解决使用reduce不是可迭代对象Javascript对对象进行迭代时出错

我想在数组 presentsData 中的每个对象中添加一个名为 money 的新字段，并使用由每个人的分数确定的值。我在其他情况下是这样做的，并且有效，但现在出现此错误： TypeError: object is not iterable (cannot read property Symbol(Symbol.iterator))error:

let presentsData= [
    {
      name: "Peter",presents: ["coffee","holidays"]
    },{
      name: "Mario",presents: ["car","coal"]
    },{
      name: "Amanda",presents: ["computer",{
      name: "David",presents: ["clothes","car"]
    }
]
 const scoresData= [
    {
      name: "Peter",score: 10
    },score: 6.3
    },score: 1.1
    },score: 8
    }
  ]

let childscore = scoresData.find(s => s.name == "Peter").score

const result = presentsData.reduce((acc,ele) => {
 console.log(ele)
                if (ele.name == "Peter") {
                    if (childscore > 8) {
                        return [...ele,money= 7000]
                    } else if (childscore < 8 && childscore > 5) {
                        return [...ele,money = 2000]
                    } else if (childscore < 5) {
                        return [...ele,money = 300]
                    }
                }
                return acc;
            },0)
console.log(result)
