vue如何把一个数组里面的数据放到另一个数组的每一项里面

Question

数据格式如下

let arr = [
    {
        "productName": "颜色",
        "productcode": "0001",
        "productId": "a80ff169-d6f6-4752-b980-fd818240410f"
    }
]

另一个数组

let arr2 = [
    {
        "productSkuName": "美年达1",
        "productSkuCode": "10",
        "productSkuId": "46f7c6ba-b4ca-4843-b5d1-76399d1ac52a",
        "remark": ""
    },
    {
        "productSkuName": "可乐1",
        "productSkuCode": "11",
        "productSkuId": "2ea2a723-1a6c-4545-92ce-2ef07547642f",
        "remark": ""
    }
]

需要把arr中的数据添加到arr2中的每一项
