The knowledge you got from the javascript flavored web components and indexDB and service workers you might have used with Angular will come in handy optimizing wasm/blazor when you realize -- wasm is still a WIP and javascript and DOM libraries are still needed. Also, I'm sure Micrsoft will support more than just C# for blazor (you interested in OCaml or F#?)
