Q&A in the description

With the rise of Web Assembly we can easily enhance JavaScript and give application(s) access to low-level processing & transform web experiences.

Q: Do platforms like ionic and wasm have a common use case?
A: Debugging / Tracing is possible if you enable the right flags when creating your wasm module - and Chrome has extra support for debugging as well: Debugging — Emscripten 2.0.4 documentation

Q: Is there a way to debug/trace web assembly in the browser? any recommended plugins for such?
A: So regarding Ionic and wasm - you could create a mobile app and still utilise web assembly, since .wasm files are like any other files that you would be using on the web or in a mobile app.

Q: What do you think about blazor which doesn't require the developer to explicity write javascript? will there be a future where webassembly is first class in browsers and won't need javascript anymore? or will web be forever be tightly coupled to javascript?
A: Regarding Blazor - since I haven't used that tool, I can't really comment. Also, web assembly is a first class in browser since browser's virtual machine understands them, allocates spaces to it (which you can read/write files from/to). However I can't really predict the future whether wasm will or will not be tightly coupled to JS. It is for now and I believe it's a really good combination
