JavaScript 过滤多层数据结构

let promotGroups = [ { "promotionId":"1111111111", "promotionName":"", "promotionDescription":"", "havePromotion":false, "classes":[ { "classId":"77777777777777", "tutorPictureUrl":"", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], "goodsType":0, }, { "classId":"1111111111111111111", "tutorPictureUrl":"", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], "goodsType":0, } ] }, { "promotionId":"2222222222", "promotionName":"", "promotionDescription":"", "havePromotion":false, "classes":[ { "classId":"6e64da1f52694f608293267c87865ce3", "tutorPictureUrl":"", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], "goodsType":0, }, { "classId":"000000000", "tutorPictureUrl":"", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], "goodsType":0, } ] }

]

我想要过滤的结果还是上面的那样只是不同的 classes 取值不一致？
请问一下怎么过滤？？
理想的结构：

let new = [ { "id":"1111111111", "newarr":[ { "id":"77777777777777", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], "goodsType":0, }, { "classId":"1111111111111111111", "tutorPictureUrl":"", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], } ] }, { "id":"2222222222222", "newarr":[ { "id":"00000000000000", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], "goodsType":0, }, { "classId":"1111111111111111111", "tutorPictureUrl":"", "teachers":[ { "teacherId":"bf2ab5882d9e470a825eee97541d8868", "teacherName":"张亚飞测试", "name":"张亚飞测试", "realName":"张亚飞测试", "sex":0, "pictureUrl":"" } ], } ] },

]

回答：

//多层map能返回你想要的结果


promotGroups.map(item => {
  return {
    id: item.promotionId, newarr: item.classes.map(val => {
      return {id:val.classId,goodsType:val.goodsType,teachers:val.teachers}
    })
  }})
