From Asm.js to WebAssembly

Re:From Asm.js to WebAssembly by BrendanEich on Wednesday June 17, 2015 @06:28PM (#9735688)

Serious question: why could not those other devs learn from your Rust code, even decompile wasm back into it via their devtools and ye olde view source?

Because the source-map may not be available. And they might not know Rust. Or perhaps having to setup a Rust dev env to play with this code is too much work and it's just not worth it.

Anyway, I think I should explain my thoughts better instead of only pointing out a problem. I wrote this comment: https://news.ycombinator.com/item?id=9743859

Sometimes you must build with -g. WebDWARF ;-).

Can you please clarify? I've seen WebDWARF mentioned twice now, but when I Google, I get a bunch of results about a shareware clone of Dreamweaver.

DWARF is a debugging data format for ELF files.[1]

WebDWARF then would be to WebASM, as DWARF is to ELF files.

I'm suggesting that when debugging optimized code, you'll use -g as on native platforms. I'm speculating further that with wasm, decompilers will rise to the view source challenge.
