What WebAssembly means for React
summary
Claim: compiling React's reconciler to WebAssembly could enable code reuse with React Native and move the fiber data into a Wasm heap so the fiber tree built in Wasm drives diffs while JavaScript still performs DOM mutations via imported functions. The prototype uses Wasm imports (memory, tables, function closures), shows short‑term overhead so the outcome is short-term: a wash or modest improvement, and outlines future wins from threading, shared memory and direct DOM/GC integration.
