Lodash sortBy method
语法：
_.sortBy(collection, [iteratees=[_.identity]])
Creates an array of elements, sorted in ascending order by the results of running each element in a collection thru each iteratee. This method performs a stable sort, that is, it preserves the original sort order of equal elements. The iteratees are invoked with one argument: (value).
参数：
collection (Array|Object) − The collection to iterate over.
[iteratees=[_.identity]] (...(Function|Function[])) − The iteratees to sort by.
输出：
(Array) − Returns the new sorted array.
例子：
var _ = require('lodash');
var users = [
{ user: 'Joe', age: 48, active: false },
{ user: 'Robert', age: 34, active: true },
{ user: 'Julie', age: 40, active: false },
{ user: 'Stafey', age: 36, active: true }
];
var result = _.sortBy(users, [function(item) { return item.user; }]);
console.log(result);
var result = _.sortBy(users, ['user', 'age']);
console.log(result);
