Generating Recurring Dates with JavaScript: A Step-by-Step Guide

The Problem

Imagine you have the following requirements:

Start Date: 2021-10-04T00:00:00Z

End Date: 2021-10-31T00:00:00Z

Recurring Date: 2021-10-05T00:00:00Z

You need to produce an array of dates occurring every week from your start date up to your end date. The expected output for this setup would look like this:

The Solution

Step 1: Define Your Dates

First, we need to specify the start and end dates. Make sure to format them as ISO strings to ensure they are recognized correctly as dates.

Step 2: Create the Function

Next, we create a function named getWeeklyDates that will take the start and end date as parameters. Within this function, we'll define a date variable to iterate through the weeks.

Step 3: Use a While Loop to Populate the Result Array

Inside the function, we will use a while loop to add dates to our array until we reach the end date. Each iteration will move the date forward by 7 days (one week).

Step 4: Convert to ISO Strings and Output the Result

Finally, we'll return the resultant array as ISO strings. This can be achieved using map() function to convert each Date object into its string representation.
