1.两个数组对象合入一起
const cc = [
  {
    id: 1,
    age: '80岁',
    name: '444',
  },
  {
    id: 1,
    age: '804岁',
    name: '2',
  },
  {
    id: 1,
    age: '803岁',
    name: '3',
  },
  {
    id: 1,
    age: '830岁',
    name: '33',
  },
  {
    id: 1,
    age: '1022220岁',
    name: '白龙马111111111',
  },
]
const reslutList = [
  {
    id: 1,
    age: 'age',
    name: '唐曾',
  },
  {
    id: 1,
    age: '500岁',
    name: '孙悟空',
  },
  {
    id: 1,
    age: '800岁',
    name: '猪八戒',
  },
  {
    id: 1,
    age: '200岁',
    name: '沙和尚',
  },
  {
    id: 1,
    age: '100岁',
    name: '白龙马',
  },
]
let op = cc.map((item, index) => {
  return { ...item, ...reslutList[index] }
})
console.log(op, 'ooooooooooooooooooooooooo')将两个数组合并为一个数组对象

let qw = ['唐曾', '孙悟空', '猪八戒', '沙和尚', '白龙马']
let err = ['30岁', '500岁', '800岁', '200岁', '100岁']
let arrObj = []
arrObj = qw.map((item, index) => {
  return { label: item, value: err[index] }
})
console.log(arrObj, 'arrObjarrObj')
