Javascript file not working on github pages

I am able to load my javascript file on the local machine. But on github pages, it is not working.

I have included the file in index.html as

<script src="script.js" type="text/JavaScript"/>

The website is https://abhikulshrestha22.github.io./

The code is at https://github.com/abhikulshrestha22/abhikulshrestha22.github.io

Any help would be appreciated. Thanks in advance.

Edit 1 I tried to add the following code in my javascript file to check if its working, but it is not working on github page and working locally.

$(document).ready(function(){
    alert("hi");}
