WebAssembly: birth of a virtual ISA

on YouTube ↗32m

" summary

Claims WebAssembly is a portable, size‑ and load‑time‑efficient compilation target for C++, rust and similar languages that runs inside the browser and shares the JS engine, delivering predictable, JIT‑quality speed and lower CPU/battery use. Demo: a GameBoy emulator compiled to WebAssembly actually runs in-browser. Toolchain used includes Emscripten → asm.js → wasm, ArrayBuffer memory, fetch + WebAssembly.compile/instantiate. Specification exists as text and compact binary; engines generate native code. Shortcut to JS engine optimizer
