Function sortBy

Creates an array of elements, sorted in ascending order by the results of running each element in a collection through 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).

Example

var users = [
  { 'user': 'fred',   'age': 48 },
  { 'user': 'barney', 'age': 36 },
  { 'user': 'fred',   'age': 42 },
  { 'user': 'barney', 'age': 34 }
];

_.sortBy(users, function(o) { return o.user; });
// => objects for [['barney', 36], ['barney', 34], ['fred', 48], ['fred', 42]]

_.sortBy(users, ['user', 'age']);
// => objects for [['barney', 34], ['barney', 36], ['fred', 42], ['fred', 48]]

_.sortBy(users, 'user', function(o) {
  return Math.floor(o.age / 10);
});
// => objects for [['barney', 36], ['barney', 34], ['fred', 48], ['fred', 42]]
