Add WebAssembly example

Just want to say this is great - I had no idea that C# WASM was so simple.

Rather than using the ReadAllAsync method, instead can you change to StartParsing/MoveNext and yield to the web UI every 17ms or so? That way the tab won't freeze up as it's parsing, and you get results live.

Many thanks

Yep, wasm support is quite cool 😎

I guess "live" parsing should be simple to add. Probably a repetitive JS timer which advances demo for 17 ms.

Or you can even go step further and run the parser in Web Worker (ie. a background thread in Web) 😄

Will see tomorrow if I have time to add it.

It's done.

I constrained it to 20 FPS, because 60 FPS increases processing time a lot. I don't know why, probably Task.Delay() has some overhead, or it's not precise to 1 ms level.
