For the past two weeks I've been evaluating Blazor. (C#) It's real nice. It comes in two flavors: Server-side that controls the browser via a websocket, or client-side that compiles C# into WASM. Server-side has the advantage that you don't have to wrap up all your APIs into contracts; client-side is a bit more "normal."
The Razor templating system is very nice. It's not like mustache where you have to learn a completely new syntax; it's very minor bits of C# and regular HTML.
I'm not sure I'd pick Blazor in a complete greenfield situation; but given that I'm working in a C# shop, it's a great way for C# developers to be full-stack while keeping the learning curve simple.
