Maybe you don't need Rust and WASM to speed up your JS
I rely heavily on a decent JS performance baseline for <a href="http://8bitworkshop.com/" rel="nofollow">http://8bitworkshop.com/</a>, and I also rely on asm.js / WASM. But I need different things from them.<p>For JS, I need consistency and stability, because I'm dynamically generating code. Usually I'm pretty satisfied, but sometimes after recompiling code I get a huge performance hit for no reason.<p>For WASM, I know I have stability, but I need faster load times. On my Chromebook, for example, it takes 10-20 seconds just to load the WebAssembly. If this problem is solved, I might move everything performance-sensitive over to WASM eventually.
