js对象键值对转换为数组对象

原对象：

{
   SF: '顺丰速运',
   DBL: "德邦快递"  
}

转换后:

[{
    label: "顺丰速运"
    value: "SF"
  },{
    label: "德邦快递"
    value: "DBL"
  }]

源码：

const obj = {
  SF: '顺丰速运',
  DBL: "德邦快递"  
}
const result = Object.keys(obj).map((el) => {
  return {
     value: el,
     label: obj[el]
  }
})
console.log(result)
