I think my javascript files are somehow not being read by Chrome. In the "Network" section of the developer tools (inspect) in Chrome, my js file has a status 404 and is colored red. The below script is the code in my html file:

<script src="js/checkout.js" type="text/javascript"></script>

The src path is correct, because vscode shows me the correct js file when I click the src=js/checkout.js of the script tag. I removed all cache from the browser, but the problem still persists. I hope you can guys can help me, and please leave a question if you have one.
