Date Is Same as Another Date

Introduction

In this lab, we will explore how to check if a date is the same as another date using JavaScript. We will be using the Date object and its toISOString() method to convert the dates to an ISO string format, which we can then compare for equality using strict equality checking. By the end of this lab, you will have a better understanding of how to compare dates in JavaScript and ensure they are the same.

Checking if Two Dates are the Same

To check if two dates are the same, follow these steps:

1. Open the Terminal/SSH and type node to start practicing coding.
2. Use Date.prototype.toISOString() and strict equality checking (===) to compare the two dates.
3. Here's an example code snippet:

const isSameDate = (dateA, dateB) =>
  dateA.toISOString() === dateB.toISOString();

4. Test the function with two dates as arguments to see if they are the same:

isSameDate(new Date(2010, 10, 20), new Date(2010, 10, 20)); // true

This function checks whether the two dates are the same by comparing their ISO string representations.
