js多层数组如何转换？

原数组：

arr1 = [
  {
    checked:false,
    fileList:[
      {
        author: "ad",
        fileName: "工作的通知(1) - 副本.docx",
        isArchive: "yes",
        version: "1"
      },
      {
        author: "ad2",
        fileName: "工作的通知(1) - 副本.docx",
        isArchive: "yes",
        version: "2"
      },
      {
        author: "ad3",
        fileName: "工作的通知(1) - 副本.docx",
        isArchive: "yes",
        version: "3"
      },
    ]
  },
  {
    checked:false,
    fileList:[
      {
        author: "cj",
        fileName: "工作的通知(2) - 副本.docx",
        isArchive: "yes",
        version: "1"
      },
      {
        author: "cj2",
        fileName: "工作的通知(2) - 副本.docx",
        isArchive: "yes",
        version: "2"
      },
    ]
  }
]

前端想将原数组转换成这种:

arr2= [
  {  
      checked:false,
      author: "ad",
      fileName: "工作的通知(1) - 副本.docx",
      isArchive: "yes",
      version: "1"
  },
  {  
      checked:false,
      author: "ad2",
      fileName: "工作的通知(1) - 副本.docx",
      isArchive: "yes",
      version: "2"
  },
  {    
       checked:false,
       author: "ad3",
       fileName: "工作的通知(1) - 副本.docx",
       isArchive: "yes",
       version: "3"
  },
  {
    checked:false,
    author: "cj",
    fileName: "工作的通知(2) - 副本.docx",
    isArchive: "yes",
    version: "1"
  },
  {
    checked:false,
    author: "cj2",
    fileName: "工作的通知(2) - 副本.docx",
    isArchive: "yes",
    version: "2"
  },
]

请问使用js方法如何转换啊？

回答：

let arr2 = [];
arr1.forEach(e=>{
  const { checked,fileList } = e;
   fileList.forEach(file=>{
     file.checked = checked;
     arr2.push(file)
   })
})
