# \_.sortBy（数组或对象排序）

**语法：**

```javascript
_.sortBy(collection, [iteratees=[_.identity]])
```

**源代码链接：**[source](https://github.com/lodash/lodash/blob/4.17.10/lodash.js#L9929)

**npm包链接：**[npm package](https://www.npmjs.com/package/lodash.sortby)

**描述：**

创建一个元素数组。 以 iteratee 处理的结果升序排序。 这个方法执行稳定排序，也就是说相同元素会保持原始排序。 iteratees 调用1个参数：*(value)*。

**开始版本：**0.1.0

**参数：**

* `collection (Array|Object)`: 用来迭代的集合。
* `[iteratees=[_.identity]] (...* (Array|Array[]|Function|Function[]|Object|Object[]|string|string[]))`: 这个函数决定排序。

**返回值：**

* `(Array)`: 返回排序后的数组。

**例子：**

```javascript
var users = [
  { 'user': 'fred',   'age': 48 },
  { 'user': 'barney', 'age': 36 },
  { 'user': 'fred',   'age': 40 },
  { 'user': 'barney', 'age': 34 }
];

_.sortBy(users, [function(o) { return o.user; }]);
// => objects for [['barney', 36], ['barney', 34], ['fred', 48], ['fred', 40]]

_.sortBy(users, ['user', 'age']);
// => objects for [['barney', 34], ['barney', 36], ['fred', 40], ['fred', 48]]
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://lodash.shujuwajue.com/collection/sortby.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
