JavaScript - sort array of objects by date property value

In this article, we would like to show you how to sort array of objects by date property value using JavaScript.

Quick solution:

array.sort(function(a, b) {
    return a.date - b.date;
});

Practical example

In this example, we sort an array of objects by date property value using the custom compare function as an argument of the sort() method.

1. Ascending order

// ONLINE-RUNNER:browser;

var array = [
    { name: 'Ann',  birthday: new Date('2000-01-02') },
    { name: 'Tom',  birthday: new Date('2000-01-01') },
    { name: 'Mark', birthday: new Date('2000-01-03') }
];

array.sort(function(a, b) {
    return a.birthday - b.birthday;
});

console.log(JSON.stringify(array, null, 4));

2. Descending order

// ONLINE-RUNNER:browser;

var array = [
    { name: 'Ann',  birthday: new Date('2000-01-02') },
    { name: 'Tom',  birthday: new Date('2000-01-01') },
    { name: 'Mark', birthday: new Date('2000-01-03') }
];

array.sort(function(a, b) {
    return b.birthday - a.birthday;
});

console.log(JSON.stringify(array, null, 4));
