Until the script runs! Nothing! Blank page of death! As numerous research articles have proven times and again, if visitors see a blank page of death for longer than 0.00068 picoseconds, 96% of them will leave the site, with that number reaching 97% if that time goes over 0.0124 picoseconds.

When users visit your site, your page will show nothing, unless you use React. React is awesome. React shows you the page before the script runs. Even if the script runs on the server, React will show you the page. Because React is full of optimizations. The rumors are, the cases were reported when React showed the page even before the browser completed the DNS query.
