    const B = {

        {
          asin: "B08FHFMW1V",
          sku: "130516"
        },
        {
          asin: "B08FHF6V8B",
          sku: "130517"

        {
          asin: "B08FHFWDVM",

        },
        {
          asin: "B08JKK4217",
          sku: "130520"
        },
        {

          sku: "130521"
        },
        {
          asin: "B08JKP82PB",
          sku: "13052221"
        },
      ],
    };

        let difference = B.ProductMetadataList.filter((page1) => {
      const result = A.forEach((element) => {
        element.portfolioData.portfolioData.find((page2) => {
          if (page1.asin === page2.asin) {
            page2.sku.includes(page1.sku);
          }
        });
      });
      return !result;
    });
    
    console.log("difference check ", difference);

无法实现上述结果，因为 page1.asin === page2.asin 不匹配，您可以 console.log(page1.asin === page2.asin) 并理解差异，因为我无法解释。

我正在努力实现：- 将 B 数组与 A 数组进行比较并从数组 B 中获取不匹配的对象。

面临的困难：- 无法检查值是否存在于数组 A - 来自数组 B 的 sku 数组 - sku 值。

只有 2 行

将A数组设为一级数组-这样会更容易找到匹配项 A.map(i => i.portfolioData.portfolioData).flat();
过滤找到的元素 B.ProductMetadataList .filter(i => !assinListA.find(j => i.asin === j.asin && j.sku.includes(i.sku)))

const A = [

一种简单易读的方法是注册匹配数据 array B 的索引，然后根据这些索引进行过滤。

注意：我减少了数组以使代码更易于阅读。它将与您的数据一起使用。

const A = [
  { 
    campaignId: "3964126695264",
    portfolioData: { 
      portfolioData: [
        { asin: "B08JKK4217", sku: ["130520"]},
        { asin: "B08JKP82PB", sku: ["130521"]}
      ]
    }
  },
  { 
  campaignId: "137244687845173",
    portfolioData: {
      portfolioData: [
        { asin: "B08JKK4217", sku: ["130520"]},
        { asin: "B08JKP82PB", sku: ["130521"]}
      ]
    }
  }
]

const B = {
  ProductMetadataList: [
    { asin: "B08JKK4217", sku: "130520"},
    { asin: "B08JKP82PB", sku: "130521"},
    { asin: "B08JKP82PB", sku: "13052221"}
  ]
}

let indexes = [] // matching indexes of array B

for(item of A){
  let portfolioData = item['portfolioData']['portfolioData']
  
  portfolioData.forEach((el_A) => {
    B.ProductMetadataList.forEach((el_B, i) => {
    
      // conditions
      let C1 = el_A.asin === el_B.asin
      let C2 = el_A['sku'].join() === el_B['sku']
      let C3 = !indexes.includes(i)
      
      // save index if there is a match and the index has not been saved before
      if(C1 && C2 && C3) indexes.push(i)
    })
  })
}

let result = B.ProductMetadataList.filter((el,index) => !indexes.includes(index))

console.log(result)
