javascript - Lodash 从另一个对象追加对象而不进行替换

Question

如何将值从另一个对象附加到一个对象而不进行替换？

我正在尝试将 ObjectA 中的值附加到 ObjectB 作为子对象的名称。

这是对象A。

正如您所知，ObjectA 有 4 个子对象，每个子对象都与一个 uid 关联。

这是对象B

因此，我尝试将每个子项的 uid 从 ObjectA 映射到 ObjectB。

这就是理想的代码

Object.keys(ObjectA).forEach(
    (key) => _.assign(ObjectB, {'Product 07': true})
)

我尝试将每个 ObjectB 迭代注入(inject)源占位符 ES6 字符串插值，但它会失败，就像这样。

Object.keys(ObjectA).forEach(
    (key) => _.assign(ObjectB, {`${basketObject[key].uid}`: true})
)

来源(JSON)

请使用此代码将对象的对象转换为带有_.mapValues的数组的对象，以从对象名称生成uid

var ObjectA = _.mapValues(data, (val, index) => {
    return { ...val, index }
})

Answer 1

应该可以

_.mapValues(ObjectA, (val) => {
    ObjectB[val.uid] = true;
})
