My experience with WASM

https://github.com/rustwasm/wasm-bindgen

Exporting classes...

wasm-pack

https://github.com/rustwasm/wasm-pack

Advantages of WASM

• Deterministic performance
• Manual memory management
• Use WASM everywhere!

Disadvantages

• Increased complexity.
• The exported library can't make use of native language features (e.g. functions as arguments).
• Rather complicated to setup.
  • Versions of wasm-pack are incompatible
  • Not just `npm i`. You need to install a load of experimental tools.
• Hard to contribute.

Ywasm?

• JavaScript's performance is close to native languages.
• It's really just about manual memory management.
• WASM can be included into PostgreSQL and CDNs
