Sprinkle it a bit with some simple JavaScript/jQuery code for animations, forms checking etc, if you want. That's it. That's how it was supposed to work and that's how it works best. JavaScript was made to make the monkey dance. The end result, either made with overcomplicates frameworks like React/Angular or with simply generating the web page on the backend, is irrelevant to the user.
Agreed with “just generate a web page on the backend”. But if the webapp is sufficiently complex (all websites I have been paid to work on have been), you need a component based framework like React to make the creation of the page manageable
