关于javascript:js新旧对象数组对比如果两个数组有相等的值id则把新数组对应的id的某一项过滤出来

    // 上一次的数据，旧数组
    var oldArray = [{ id: '1', name: 'zhangsan', age: '15'},
      {id: '2', name: 'lisi', age: '16'},
      {id: '3', name: 'ani', age: '17'},
    ]
    // 刚刚返回的新数组
    var newArray = [{ id: '1', name: 'zhangsan', age: '100'},
      {id: '2', name: 'lisi'},
    ]

    // 将旧数组过滤出符合条件的数据 id 汇合
    const idsArray = oldArray.filter((item) => {return item.id !== '1'}).map((item) => {return item.id});

    console.log(idsArray, 'idsArray');
    // ['2', '3'] 'idsArray'




    const productList = newArray.filter((item) => {return idsArray.includes(item.id)
    })
    console.log(productList, 'productList')
    // [{id: '2', name: 'lisi'}] 'productList'
