It will depend on the site.
Some sites you can totally disable JS, and they work fine. Often better! It can avoid the annoyware in so many sites now.
Other sites require JS for basic functionality. But also have tons of tracking JS. On those you can disable the tracking JS and run only what is required.
Yet other sites are such a clusterfuck from many 100’s of demains and it can be hard or impossible to unravel what is needed. Those I try to avoid the site if I can.
Someone always will say disabling JS is a fingerprint too. Which is true, but misleading, b/c you can reduce the bits of info more by disabling JS than the bits obtained by the site seeing you disabled JS.
