How to Retrieve All Dates of the Current Week in JavaScript

Every week brings new opportunities to plan your tasks, schedule events, or just keep track of important dates. If you're developing a web application using JavaScript and need to get all the dates of the current week, you're in the right place! In this guide, we’ll explore how to generate an array of dates for the entire week, given today's date.

The Problem Explained

Suppose today is 11/22/2021 (November 22, 2021). If you want an array that includes all the dates from Sunday to Saturday of that week, it would look like this:

This array should remain consistent until the next Sunday, at which point a new array will be created for the following week. Let's delve into how we can achieve this using JavaScript.

The Solution

Step 1: Initialize an Array

To get started, we need to create an empty array that can hold the dates of the week. The JavaScript method Array(7) creates an array with a length of 7 (one for each day of the week).

Step 2: Use Array Keys

Next, we'll utilize Array(7).keys() to return an iterator with the keys of our array. This will help us access indices from 0 to 6, which represent the days of the week.

Step 3: Transform to an Array

This gives us [0, 1, 2, 3, 4, 5, 6], representing the indices we need to determine each day of the current week.

Step 4: Calculate Each Day's Date

Finally, we’ll iterate through our numeric array using map(). For each index, we’ll calculate the corresponding date by adjusting from the current date:

Explanation of the Code

new Date() initializes a date object with the current date.

The result will be an array that consists of the Date objects corresponding to each day of the current week. You can easily format these dates according to your preferred style.

Conclusion

Getting all the dates of the current week in JavaScript is straightforward once you know the steps involved. By utilizing key JavaScript array methods and the Date object, you can create a dynamic solution that adapts to the current week effortlessly.

Feel free to implement this code in your applications to manage weekly schedules or event planning effectively! Happy coding!
