javascript 迭代和重新映射

Question

我有一个如下所示的数据集:

const data = [["customer1",29349,3654],["customer2",29349,3654],["customer3",15178,130]

我需要使用 map 将数据转换为此。

series: [{
    category: 'Resolved before conciliation',
    data: [29349, 29349, 15178]
}, {
    category: 'Conciliation successful',
    data: [3654, 29349, 130]
}]

我尝试了以下方法，这让我获得了第一个类别，但我似乎无法弄清楚如何将第二个类别添加到同一张 map 中的系列中。

const series = [{
    name: 'Resolved before conciliation',
    data: data.map(([...data]) => (data[1]))
}]

console.log(JSON.stringify(series))

输出:

[{"name":"Resolved before conciliation","data":[29349,29349,15178]}]

Answer 1

使用reduce分组:

const data = [["customer1",29349,3654],["customer2",29349,3654],["customer3",15178,130]];

let reduced = data.reduce((results, arr) => {
   results[0].data.push(arr[1]);
   results[1].data.push(arr[2]);
   return results;
}, [{ category: 'Resolved before conciliation', data : [] }, { category: 'Conciliation successful', data : [] }]);

console.log(reduced);
