合并2个数组，更新值

Question

在我的化简器中，我要从API中提取结果，我想将此数组与存储中的持久数据（如果存在）结合起来，数据中唯一需要覆盖的字段是bookMarked， totalScore和completed。我如何比较数组并覆盖所需的属性（如果它们不同）？

最好的方法是什么？

let arrayFromAPI= [
    {
        bookMarked: false,
        completed: false,
        totalScore: 50,
        current: 0,
        description:
            "<p>Lorem ipsum culpa qui officia deserunt mollit anim id est laborum.</p>",
        icon: "male-urinary-catheterisation",
        id: 1
    },
    {
        bookMarked: false,
        completed: false,
        totalScore: 50,
        current: 0,
        description:
            "<p>Lorem ipsum culpa qui officia deserunt mollit anim id est laborum.</p>",
        icon: "male-urinary-catheterisation",
        id: 2
    }
];

let arrayFromPersist = [
    {
        bookMarked: true,
        completed: false,
        totalScore: 50,
        completed: true,
        current: 0,
        description:
            "<p>Lorem ipsum culpa qui officia deserunt mollit anim id est laborum.</p>",
        icon: "male-urinary-catheterisation",
        id: 1
    },
    {
        bookMarked: true,
        completed: false,
        totalScore: 50,
        completed: true,
        current: 0,
        description:
            "<p>Lorem ipsum culpa qui officia deserunt mollit anim id est laborum.</p>",
        icon: "male-urinary-catheterisation",
        id: 2
    }
];

您可以使用过滤器并根据属性ID将arrayFromAPI响应中的所有值合并到arrayFromPersist，因为两个数组中的值必须相同才能替换{{ 1}}
