Thankfully most of our Web projects keep being SSR in Java and .NET stacks, with minimal JavaScript.
Why is React superior to Razor Templates (or for that matter, Razor pages) for server side templating?
I support the assertion that it’s a good paradigm for creating consumable SSR templates I just don’t see anything that empirically cuts it above Razor other than if you know JSX/JavaScript it’s obviously more natural but I’m assuming that’s taken for account here
If you don't want to dig too deep though, compare how to add a datepicker to a view in both systems. With React it is just another component, with Razor it is a bit more finicky.
