Function lodashSortBy

  • 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).

    Type Parameters

    • T

    Parameters

    • collection: undefined | null | List<T>

      The collection to iterate over.

    • Optional...iteratees: Many<ListIteratee<T>>[]

      The iteratees to sort by, specified individually or in arrays.

    Returns T[]

    Returns the new sorted array.

    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]]

    Parameters
