求助大佬,关于数组用JS改变数据格式问题?

    一个数据格式是这样的：

    a:[
    [{id: "12", lottery_id: "1", type_id: "37", type: "commodity", image: "XX.png"}],
    [{id: "11", lottery_id: "1", type_id: "37", type: "commodity", image: "XX.png"}],
]

    把他转换成这样

    b:[
    { fonts: [{ text: '0', top: '10%', id: "12", lottery_id: "1",}],image: "XX.png" },
    { fonts: [{ text: '1', top: '10%', id: "11", lottery_id: "2",}],image: "XX.png" },
]

    用JS需要怎么做？

let b = a.map(([{ id, lottery_id, image }], index) => ({
    fonts: [
        {
            text: String(index),
            top: "10%",
            id,
            lottery_id,
        },
    ],
    image,

  // 转换数据格式
  const transformedData = {

      return {
        fonts: [{ text: index.toString(), top: '10%', id, lottery_id }],

  console.log(transformedData);
