“集合” 方法(“Collection” Methods)
_.sortBy(collection, [iteratees=[_.identity]])
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)。

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。(Array): 返回排序后的数组。
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]] _.sortBy(users, 'user', function(o) { return Math.floor(o.age / 10);});// => objects for [['barney', 36], ['barney', 34], ['fred', 48], ['fred', 40]]
