将多维json数组中的一组属性列入白名单，并删除其余部分

Question

例如，我将使用github API响应作为我的数据输入。

https://api.github.com/users/unsalted/repos

我有我想继续，我想放弃，因为我想保持输出我生成相当多的紧凑其余属性的列表。

我如何能实现我的目标没有这样做：

 for (var i = tagged.length - 1; i >= 0; i--) { 
      delete tagged[i].private; 
      delete tagged[i].owner.gravatar_id; 
      delete tagged[i].owner.url; 
      delete tagged[i].owner.followers_url; 
      delete tagged[i].owners.following_url; 
      delete tagged[i].gravatar_id; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 
      delete tagged[i].private; 

     }; 

我在项目中使用lodash所以lodash解决方案更受欢迎。

对于时间的缘故，我没有填写值的其余部分，但你的想法...

对于一个给定的对象，你可以使用_.pick让您指定的唯一性;然后你可以将它映射到你的收藏。所以，你最终得到：

tagged = _.map(tagged, function (t) { 
    return _.pick(t, ['properties', 'to', 'keep']); 
});
