我希望返回一个对象数组，其中包含一个对象的子数组。
我提取的数据包含一个“projects”数组，该数组中包含一系列属性，该数组中包含一个“work items”数组。我想循环/Map"projects“数组并返回一个新的对象数组，其中将有一个”subtasks“属性，该属性需要包含另一个对象数组，该对象数组是从”projects“数组中的”work items“数组开发的。
下面是我到目前为止所做的。这不是我想要的，因为我需要在循环项目时创建主对象，然后在循环“工作项”时创建“子任务”数组。我试图将总体对象放在“return project.workItems.map...”行上方，但我得到了语法错误。
请参阅下面的代码以获得预期输出的示例。

let newProjects1 = projects.map((project, index) => {

  return project.workItems.map((workItem) => {
    return {
      TaskID: index,
      ProjectNo: project.projectNumber,
      TaskName: project.projectTitle,
      StartDate: new Date("11/11/2024"),
      EndDate: new Date(project.projectEnd),
      subtasks: [
        {
          TaskID: index,
          TaskName: workItem.name,
          StartDate: new Date("11/11/2024"),
          Duration: 80,
          Progress: 150,
        },
      ],
    };
  })
;

字符串
}）;
最终的输出结果应该是这样的

[
{
  TaskID: 1,
  ProjectNo: "29895",
  TaskName: "Stoneybridge WTW",
  StartDate: new Date(projects[0].projectStart),
  EndDate: new Date(projects[0].projectEnd),
  subtasks: [
    {
      TaskID: 1.1,
      TaskName: "Sodium Carbonate",
      StartDate: new Date(projects[0].projectStart),
      Duration: 4,
      Progress: 150,
      comments: "unlucky",
      subtasks: [
        {
          TaskID: 1.11,
          TaskName: "Design",
          StartDate: new Date(projects[0].projectStart),
          Duration: 30,
          Progress: 150,
        },
        {
          TaskID: 1.12,
          TaskName: "Workshop",
          StartDate: new Date(projects[0].projectStart),
          Duration: 30,
          Progress: 150,
        },
        {
          TaskID: 1.13,
          TaskName: "Site",
          StartDate: new Date(projects[0].projectStart),
          Duration: 30,
          Progress: 150,
        },
      ],
    },]
