Sorting an Array of Date Ranges in TypeScript

Handling dates can often pose a challenge, especially when they are represented as strings. A common scenario is when you need to sort an array of date ranges, and the dates are in the format MM-YYYY. This guide will guide you through the process of sorting an array of date ranges using TypeScript, ensuring that the latest date range appears first in the list. Let’s dive right in!

The Problem

Suppose you have an array of date ranges like this:

Your goal is to sort this array in such a way that the latest date range comes first. Since the dates are in string format, a direct comparison won't yield the intended results. Instead, we need to convert them into a comparable format.

The Solution

To accomplish this task, we'll implement a utility function that converts the date strings into a format that's easy to compare. We will then sort the array using this method.

Step 1: Create a Function to Format Dates

First, we need a helper function that will transform date strings into a YYYY-MM format for easier comparison:

Step 2: Sort the Array Using Custom Logic

Next, we will use the sort() method in JavaScript, leveraging our helper function to sort the date ranges based on their start and end dates. Here’s how to do it:

Conclusion

Sorting an array of date ranges in TypeScript can be achieved by converting the date strings into a comparable format. By using the combination of string manipulation and JavaScript’s sorting methods, we can effectively achieve the desired results. Now you can handle date ranges efficiently in your TypeScript projects!

Feel free to experiment with this code and adapt it to suit your needs. Happy coding!
