JAVASCRIPT VS. WEBASSEMBLY

PERFORMANCE COMPARISON

This is a simulation of the wave equation ∂²u/∂t² = c²(∂²u/∂x²+∂²u/∂y²) across a circular 2D manifold. Use the mouse to create waves.

This compares a standard Javascript implementation against several different WebAssembly modules:

• C code compiled by Emscripten
• C code compiled by WebAssembly Studio (Clang / Binaryen)
• TypeScript-like code compiled by AssemblyScript, with and without optimization
• JS-like code compiled by Walt
