Question

    name: \"Joe Blow\",
    date: \"Mon Oct 31 2016 00:         


        

Answer 1

Your date values are strings, so you need to use the new Date() constructor to change them to javascript date objects. This way you can sort them (using _.sortBy).

var myArray = [
  {
    name: "Joe Blow",
    date: "Mon Oct 31 2016 00:00:00 GMT-0700 (PDT)"
  },
  {
    name: "Sam Snead",
    date: "Sun Oct 30 2016 00:00:00 GMT-0700 (PDT)"
  },
  {
    name: "John Smith",
    date: "Sat Oct 29 2016 00:00:00 GMT-0700 (PDT)"  
  }
];

myArray = _.sortBy(myArray, function(dateObj) {
  return new Date(dateObj.date);
});

console.log(myArray)
