What WebAssembly means for React
summary
Argues that rewriting the reconciler in WebAssembly (C or Rust) means downloading a .wasm module and using WebAssembly.instantiate with Imports (memory, tables, functions) so the module builds the Fiber tree in its own memory while JS applies DOM changes via function imports. Claims decode/compile and execution can be faster (execution anywhere from 10% to 800% faster), but short‑term impact is a wash or modest win; longer term Threads, SharedArrayBuffer, direct DOM and GC integration promise larger gains.
