I’ve been wondering about this for a while and haven’t really found a great answer for it. From what I understand, WASM is:
Faster than JavaScript
Has a smaller file size
Can be compiled to from pretty much any programming language
Can be used outside of the browser easier thanks to WASI
So why aren’t most websites starting to try replacing (most) JS with WASM now that it’s supported by every major browser? The most compelling argument I heard is that WASM can’t manipulate the DOM and a lot of people don’t want to deal with gluing JS code to it, but aside from that, is there something I’m missing?
Unless it has improved since last time I used it then it’s awful to debug in the browser. I hate JavaScript, but would probably still use it for a new web project now.
If you use rust and structure your program correctly you can avoid debugging directly by building unit tests in language the verify behavior. Debugging tools are great and I look forward to better dx stories there (you can use chrome + DWARF to debug your native code) but strictly speaking it isn’t necessary most of the time.
Can you please elaborate on how, when using Rust, we can avoid needing to debug our JS code? I am very interested and hope that I didn’t misunderstand you.
