This guide will help you understand how to achieve this in JavaScript by breaking down the process, providing you with a clear and effective solution. The Problem Suppose you have an array of objects where each object contains a date property formatted as "mm-dd", as shown below: [[See Video to Reveal this Text or Code Snippet]] Your goal is to sort this array so that the objects are ordered based on how close their date values are to the current date. As an example, if the current date is November 29th, you want the sorted array to look like this: [[See Video to Reveal this Text or Code Snippet]] The challenge arises because simply converting the string dates to a Date object won't yield correct results since the years won't match. Let's explore a solution. The Solution To sort the array based on the current date, we can follow these steps: Step 1: Convert the Current Date We need to format the current date in the same way as our date strings in the array — as "mmdd". Here's how you can do this: [[See Video to Reveal this Text or Code Snippet]] Step 2: Implement the Sorting Function Next, we can use the sort method along with Math.abs() to compare the difference between the current date and the dates in our array. Below is the complete sorting function: [[See Video to Reveal this Text or Code Snippet]] This approach finds the absolute difference between the formatted current date and the dates in the array, effectively allowing us to sort based on proximity to today. Example Code Here’s the complete code that you can use: [[See Video to Reveal this Text or Code Snippet]] Optional: Handling Future Dates If you only want to sort dates that are in the future or present, you can follow a slightly different approach. Here's how: Convert the dates to a standard format. Calculate the current date in the form of a timestamp, and then map the original array to include these timestamps for sorting. Example Code for Future Dates [[See Video to Reveal this Text or Code Snippet]] Conclusion Sorting an array based on the current date involves converting the date strings and applying a sorting function that considers proximity to the current date. With the approaches outlined above, you can successfully sort date values efficiently, whether you're considering past, present, or future dates.
