javascript - 如何通过下划线更改集合结构？

Question

我目前的收藏如下:

[
  {Tom:true,age:23},
  {Jack:true:age:22},
  {Lucy:false,age:22}
]

如何将其转换为下划线形式？

[
  {name:'Tom',isMale:true,age:23},
  {name:'Jack',isMale:true,age:22},
  {name:'Lucy',isMake:true,age:22}
]

Answer 1

您可以使用reduce (瑞士军刀迭代器)复制内部对象，同时重新排列 name 和 isMale 值。像这样的事情:

_(a).map(function(o) {
    return _(o).reduce(function(memo, v, k) {
        if(k === 'age') {
            # Copy 'age' through as-is
            memo[k] = v
        }
        else {
            # Assume the rest is name:boolean so bust it apart
            memo.name   = k;
            memo.isMale = v;
        }
        return memo;
    }, { });
});
