A JavaScript function to provide more flexible sorting for Array.prototype.sort()

Usage

Sample Data

var data = [
  {
    id: 3,
    name: {
      first: "Bul",
      last: "Basaur"
    },
    gender: "M"
  },
  {
    id: 2,
    name: {
      first: "Char",
      last: "Mander"
    },
    gender: "F"
  },
  {
    id: 1,
    name: {
      first: "Squir",
      last: "Tle"
    },
    gender: "M"
  }
];

Example 1: Sort by single field

data.sort(sort_by("id"));

Example 2: Sort by multiple field and nested json

data.sort(sort_by("name.first", "name.last"));

Example 3: Sort by reverse order

data.sort(sort_by({ name: "id", reverse: true }));

Example 4: Sort by last name ignore case (custom primer)

data.sort(sort_by({ name: "name.last", primer: function(a) { return a.toUpperCase() } }));
