如何在JavaScript数组中将两个字符串字段连接成一个字符串？

Question

我有一个如下所示的数组：

[
  {"firstName": "john", "lastName": "doe", "linkedInID":"..."},   
  {"firstName": "jane", "lastName": "doe", "linkedInID":"..."},
  {"firstName": "someone", "lastName": "Mc Donald", "linkedInID":"..."},
  ...
]

我希望将它合并到：

[
  {"Name": "john doe", "linkedInID": "..."},   
  {"Name": "jane doe", "linkedInID": "..."},
  {"Name": "someone Mc Donald", "linkedInID": "..."},
  ...
]

所有新对象都应包含Name和firstName的串联字段lastName。

我该怎么做？

为什么你需要Angular呢？一种可能性是使用原生的.map() javascript方法来转换输入数组：

var inputArray = [
    {"firstName":"john","lastName":" doe","linkedInID":"..."},   
    {"firstName":"jane","lastName":"doe","linkedInID":"..."},
    {"firstName":"someone","lastName":"Mc Donald","linkedInID":"..."},
    ...
];

var result = inputArray.map(function(item) {
    return {
        Name: item.firstName + ' ' + item.lastName,
        linkedInID: item.linkedInID
    };
});
