Sort objects in array by date property in javascript?

Question

I have a JavaScript multidimensional array:

var people = [
    { id: 1, name: "Hannah", birthdate: "04/16/2002" },
    { id: 2, name: "Sofia",  birthdate: "03/18/2012" },
    { id: 3, name: "Robert", birthdate: "12/22/1997" },
];

How can I sort them by their birthday date?

Answer 1

you sort a birthday date value like:

var people = [
    { id: 1, name: "Hannah", birthdate: "04/16/2002" },
    { id: 2, name: "Sofia",  birthdate: "03/18/2012" },
    { id: 3, name: "Robert", birthdate: "12/22/1997" },
];

people.sort(function(a, b) {
  var dateA = new Date(a.birthdate);
  var dateB = new Date(b.birthdate);
  return dateA - dateB;
});

console.log(people);
