How to Generate an Array of Dates Within a Given Range in JavaScript?

Generating an Array of Dates within a Given Range in JavaScript

In JavaScript, you may encounter the need to create an array of dates between two specified dates. This can be a challenging task, especially when dealing with month and year boundaries.

To address this issue, let's explore a solution using JavaScript's Date object.

Custom Extension for Adding Days to a Date

First, we'll extend the Date prototype to include an addDays() method. This method takes the number of days to add to the date and returns a new Date object reflecting the adjusted date.

Date.prototype.addDays = function(days) {
    var date = new Date(this.valueOf());
    date.setDate(date.getDate() + days);
    return date;
}

Function to Get an Array of Dates

Next, we'll define a function called getDates() that takes two Date objects as parameters: a startDate and a stopDate.

function getDates(startDate, stopDate) {
    var dateArray = new Array();
    var currentDate = startDate;
    while (currentDate <p><strong>Implementation</strong></p><p>This function initializes an empty array called dateArray. It then starts with the startDate and moves forward one day at a time using the addDays() method until it reaches or surpasses the stopDate. For each valid date, it adds a new Date object to the dateArray.</p><p>The following code demonstrates the usage of these functions:</p><pre class="brush:php;toolbar:false">var range = getDates(new Date(), new Date().addDays(7));

This code creates an array of Date objects representing the days between today and 7 days from today, including today. The range variable will contain an array of date objects.
