vue 数据处理的问题

Question

数据如下，每一项的image根据attributeValue来赋值,所有的arrtibuteValue1相同值的image是一样的，比如第一项attributeValue1的值是"P.Ⅰ", 并且这一条的image是有值的话那么所有attributeValue1 等于p.I 的image都被赋值，attributeValue1的值会有多个，相同值的image是一样的，如果attributeValue1的image都没有值得话，以此类推attribute2,3,4... 优先级按照数字的顺序,应该如何修改，感谢各位

let arr = [
    {
        "image": "https://lumall.inspures.com/images/product/6985e333-dd45-45dc-b496-889400f1eb9a.png",
        "uniqueCategoryKey": "11,21,31",
        "attributeName1": "种类1",
        "attributeValue1": "P.Ⅰ",
        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "免税"
    },
    {
      
        "image": "https://lumall.inspures.com/images/product/7a2a169a-c08c-4492-914a-e6f878c3b204.png",
        "uniqueCategoryKey": "11,21,32",
        "attributeName1": "种类1",
        "attributeValue1": "P.Ⅰ",
        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "缓凝"
    },
    {
     
        "image": "",
        "uniqueCategoryKey": "12,21,31",
        "attributeName1": "种类1",
        "attributeValue1": "P.Ⅱ",
        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "免税"
    },
    {
    
        "image": "",
        "uniqueCategoryKey": "12,21,32",
        "attributeName1": "种类1",
        "attributeValue1": "P.Ⅱ",
        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "缓凝"
    }
]

想要的数据格式，相同attributeValue1这一项的image是相同的，优先去找attributeValue1的image如果没有继续往下找，以此类推

[
    {
      
        "image": "https://lumall.inspures.com/images/product/6985e333-dd45-45dc-b496-889400f1eb9a.png",
        "uniqueCategoryKey": "11,21,31",
        "attributeName1": "种类1",
        "attributeValue1": "P.Ⅰ",
        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "免税"
    },
    {
       
        "image": "https://lumall.inspures.com/images/product/6985e333-dd45-45dc-b496-889400f1eb9a.png",
        "uniqueCategoryKey": "11,21,32",
        "attributeName1": "种类1",
        "attributeValue1": "P.Ⅰ",
        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "缓凝"
    },
    {
       
        "image": "https://lumall.inspures.com/images/product/7a2a169a-c08c-4492-914a-e6f878c3b204.png",
        "uniqueCategoryKey": "12,21,31",
        "attributeName1": "种类1",
        "attributeValue1": "P.Ⅱ",
        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "免税"
    },
    {
       
        "image": "https://lumall.inspures.com/images/product/7a2a169a-c08c-4492-914a-e6f878c3b204.png",

        "attributeName2": "强度2",
        "attributeValue2": "32.5",
        "attributeName3": "其他",
        "attributeValue3": "缓凝"
    }
]
