To add to what ruicaridade said:

It quasi enables it, a NextJS site has three rendering stages:
1. static at build time
2. server side at request time
3. dynamic in the browser
It leverages React hydration for 1-2 and client side React for 3.
If you avoid 3, or rather build your site with progressive enhancement in mind (`noscript` can help but is often not necessary) then this framework makes it very easy for you.
I think https://reactjs.org/ is built with Gatsby (a similar framework, but not as dev friendly in my opinion). And you can browse it just fine with JS off last time I checked.
