JavaScript has it benefits, live updates and interaction! I'm programming myself with it because I have to do so. But the current usage of JavaScript is driven by cost savings and manipulating users and not actual technical needs. I blame especially Mozilla, that they didn't stop that early. The removal of the option to turn off JavaScript from the GUI was wrong. I can recommend as test for you, to turn off JavaScript (about:config -> javascript) and check out how web works for you. You will notice that Amazon works well and quick, it is a website. You will lose some comfort features on Stackoverflow, but still a website. Single-Page-Applications will not work - but at least you won't download unknown JavaScript from CDNs and your webbrowser will not execute it and spin up your fan. Interesting enough it are news website which tend to break, their advertisment-networks and paywalls need JavaScript. Of course there are good single-page-applications and there is stuff, which is better handled solely online. The old 3270-Emulations are an example for this. In most cases your professional users will appreciate desktop-applications, which store data locally, work fast and reliable stand-alone and uses server for syncing but not for execution. Updates could be part of the synchronization or you use modern stuff like FlatPak. Yep - you will have to pay application developers for this which will cost you money. But money? If done right you won't need to close your supermarkets next time you have an server outage, your clients switch to standalone mode and sync later the bills to the servers. That can safe a lot of money. And your admins can fix the server in meanwhile. As a consequence the web will be maybe a lot of faster and safer, too.
