Coi is a new component-based language that compiles to WebAssembly and claims superior performance over React and Vue. It uses a shared memory architecture with command and event buffers to minimize JS/WASM interop overhead, achieving 100 FPS vs Emscripten's 40 FPS in canvas rendering benchmarks. The compiler performs static analysis to enable O(1) reactivity without virtual DOM diffing, mapping state changes directly to command buffer handles. The language compiles to C++ as an intermediate step and features automatic standard library generation from WebCC schema files for browser APIs.
