Summary u Server- and client-side rendering each come with pros and cons u With Universal JavaScript, we can run the same code on both client and server, but truly taking the best of both worlds can be complex u Next.js for React is a great solution that overcomes the complexity u Rapid set-up – preconfigured Webpack + Babel that is still customizable u Minimal convention framework where routes are defined by files in a /pages/ folder u Automatic code-splitting for each page in /pages/ u Can asynchronously load anticipated pages after the current page has rendered u Developer writes one set of (universal) code that the app runs on server or client, whichever is best for the current situation
