使用foreach循环是从对象数组中删除键+值对的正确方法

Using foreach loop is it correct way to delete key + value pair from array of objects

推荐答案

如果那个是你拥有的唯一结构可以这样做

if that one is the only structure you have you can do this

result = result.map(e => ({ id: e.id }))

或者如果结构复杂得多，你可能想要使用 delete ：

or if the structure is far more complicated, you might want to use delete:

result.forEach((e) => {
    delete e.b;
});
