Ask HN: For one-way publishing websites, are JavaScript UI frameworks helpful?

Say you're building a web SITE (not a web APPLICATION).

This is a site that simply publishes content. There's no elaborate functionality or interactivity, other than a few web forms. The use cases is "click a link, view a page, click another link, view another page, etc."

Can a full JavaScript UI framework like React or Svelte provide value here? Are they worth the trouble over simple server-side templating/rendering of HTML (SSR)? Why or why not?
