怎么把后端返回的数组拆分

Question

后端返回的数组是这样的

"data":[{
            "otherAmount": 816.68,
            "proportion": 21.34,
            "thisAmount": 221.6,
            "type": "生活垃圾"
        },
        {
            "otherAmount": 0.36,
            "proportion": 100,
            "thisAmount": 0,
            "type": "含油污水"
        },
        {
            "otherAmount": 7553,
            "proportion": 0.01,
            "thisAmount": 0.6,
            "type": "生活污水"
        }]

需要把它变成这样的数组

"allData":[{
            "lable":"对比数量"
            "amount": 816.68, // "otherAmount": 816.68,
            "proportion": 21.34,
            "type": "生活垃圾"
        },
        {
            "lable":"对比数量"
            "Amount": 0.36, // "otherAmount": 0.36,
            "proportion": 100,
            "type": "含油污水"
        },
        {
            "lable":"对比数量"
            "amount": 7553, // "otherAmount": 7553,
            "proportion": 0.01,
            "type": "生活污水"
        }，
        {
            "lable":"选择数量"
            "proportion": 21.34,
            "amount": 221.6, // "thisAmount": 221.6,
            "type": "生活垃圾"
        },
        {
            "lable":"选择数量"
            "proportion": 100,
            "amount": 0, // "thisAmount": 0,
            "type": "含油污水"
        },
        {
            "lable":"选择数量"
            "proportion": 0.01,
            "amount": 0.6, // "thisAmount": 0.6,
            "type": "生活污水"
        }]

就是把数组拆分一下，把thisAmount和otherAmount放入不同的新内容里面，同时给与lable

Answer 1

let allData = data.map(item => {
    return {
        lable: '对比数量',
        amount: item.otherAmount,
        proportion: item.proportion,
        type: item.type,
    }
})

// allData
// [
//   {lable: '对比数量', amount: 816.68, proportion: 21.34, type: '对比数量'},
//    {lable: '对比数量', amount: 0.36, proportion: 100, type: '对比数量'}
// ]

Answer 2

遍历数组，每一次给新数组赋值两次，给一个label
