How to sort an Array of Objects by Date Property in JavaScript: A Step-by-Step Guide

Sorting an array of objects by a specific property, such as a date property, is a common task in JavaScript programming. In this article, we will cover the various ways to sort an array of objects by date in JavaScript.

JavaScript Sort method

The most basic method to sort an array of objects is to use the built-in sort() method, which sorts the array in ascending order by default. However, this method can only sort simple data types such as numbers or strings. To sort an array of objects by date property, we will need to pass a sorting function to the sort() method.

Here is an example of how to sort an array of objects by the date property in ascending order:

Sort an Array of Objects by Date Property

In the above example, we have created an array of events, each with a name and a date property. We then use the sort() method and pass in a sorting function that compares the date property of two objects and returns a negative value if the first object’s date is earlier, a positive value if the latter object’s date is earlier, and 0 if the dates are the same. This results in the array being sorted in ascending order by the date property.

To sort the array of objects by date property in descending order, we can simply reverse the order of the a and b parameters in the sorting function and negate the returned value.

Another way to sort an array of objects by date property

Another popular method to sort an array of objects by date property is to use the Array.prototype.sort() method in combination with the Date.prototype.getTime() method. This method converts the date property of each object to a timestamp and then sorts the array based on the timestamp.
