Learn how to bypass the JavaScript-WebAssembly boundary bottleneck by using linear memory and the pointer-offset pattern for high-performance data processing.
Learn how to accelerate browser image processing with WebAssembly SIMD. A step‑by‑step guide from a 4K grayscale benchmark to a C example, Emscripten compile flags, performance verification, and trade‑offs.
Linear memory is WebAssembly’s isolated byte array. This guide shows how to create, grow, and access it from JavaScript, pass pointers for strings, test limits, and avoid common pitfalls.
PyScript runs Python in WebAssembly with a single-threaded event loop. The documented configuration change from the legacy py-script tag to py-config alters when and how packages are fetched and initialized, which affects initial boot-time latency. Under concurrent requests, the Micodide/Pyodide runtime still relies on a Global Interpreter Lock within a sing
