JavaScript 提取对象数组中的属性组成新的对象数组

let data = 
[{"division_name":"销售三部","id":44,"pid":36,"html":"|-----"},
{"division_name":"销售十二组","id":46,"pid":44,"html":"|-----|-----"},
{"division_name":"销售十一组","id":45,"pid":44,"html":"|-----|-----"},
{"division_name":"销售二部","id":38,"pid":36,"html":"|-----"} ]

let temp = data.map((item,index)=>{
  return Object.assign({},{         
  division_name:item.division_name,id:item.id })  
}

temp
 [{"division_name":"销售三部","id":44},
{"division_name":"销售十二组","id":46},
{"division_name":"销售十一组","id":45},
{"division_name":"销售二部","id":38} ]
