# XNOR Calculator Using JavaScript with HTML

Hello Friends Today, through this tutorial, I will tell you How to Create XNOR Calculator Using JavaScript with HTML? Below is an example of an XNOR calculator using HTML and JavaScript. This example assumes that you want to calculate the XNOR (equivalence) of two binary values.

This HTML file includes two input fields for entering binary values, a button to trigger the XNOR calculation, and a result paragraph to display the calculated XNOR result. The `calculateXNOR` function converts the binary strings to integers, performs the XNOR operation, and displays the result on the page.
