凸起的和老式的对象中为您提供一个“顶部”数组。当然
这将从凸起的和老式的对象中为您提供一个“顶部”数组。您现在可以采取以下措施：
result = data.children
.filter(o => o.name === 'Age')
.map(o => Object.assign(
{},
o,
{ children: o.children.filter(p => ['Female', 'Male'].includes(p.name)) }
));

您不想在新的JSON中使用cake
？请提供您正在使用的输入和相应的所需输出的最小示例。以及您自己所做的任何尝试。请添加想要的结果。我没有看到任何JSON？在我看来像一个数组？@NinaScholz我确实修改了JSON和所需的输出。谢谢。你不想在新的JSON中使用cake

很简洁，但不幸的是它在比箭头函数更多的浏览器中仍然有效：）是的。愚蠢的我。@SNT-我想读点浅显的东西->@NinaScholz我修改了我的JSON，不能用你的代码创建新的JSON。如果您可以检查此（）并让我简单解释一下代码的作用。因此，如果我的JSON发生了更改，我可以相应地修改它。includes
