here is my index= https://github.com/25garcial/calculator/blob/main/index.html
here is my JavaScript= https://github.com/25garcial/calculator/blob/main/script.js
I don't know what is wrong with the code and i have asked my teacher and he does not know either.
Replace script tag in your index file with this :
<script src="script.js"></script>
At the bottom of the body tag in index.html file link your Javascript file with a script tag:
<script src="./yourfilename.js"></script>
To link your script try using:
<script src="script.js"></script>

Also note: You can use the defer attibute if you want your script to load after the HTML parsing and loading rather than putting it at the end of your body.
<script src="script.js" defer></script>
