参考

```javascript
注意：arr1 是基础 把arr2合并到arr1中 ，汇成一个总的arrs  这个arr1中的id 和  arr2中的periodId  是一一对应的。
let arr1 = [
 {id:64,period:"10:00"},
 {id:65,period:"12:00"},
 {id:66,period:"14:00"},
 {id:67,period:"18:00"},
]
let arr2 = [
    {   
        period:'10:00',
        periodId: 64,
        products:[
        {
            goodName: "套餐测试A-001",
            goodSn: "1368017317954457600",
            id: 252,
            limitedNum: 1,
            productId: 1658,
            remark: null,
            seckillPeriodId: 64,
            seckillPrice: 1,
            seckillStock: 1,
            skuId: 2947,
            status: 4,
            stock: 97,
            unitPrice: 100,
       }
      ]
  }
]
 const arrs = arr1.map(item => {
    const data = arr2.find(i => item.id == i.periodId)
    return {
      ...item,
      ...data,
      products: data ? data.products : []
    }
  })
console.log(arrs)
