AssemblyScript: TypeScript on Steroids Thanks to WebAssembly?

on YouTube ↗29m

" summary

AssemblyScript compiles TypeScript-like code to WebAssembly using the asc tool and a config file, producing a .wasm module plus TypeScript bindings for interop. It targets CPU-heavy workloads (big integer and bitwise operations) and shows large speedups—examples include Mandelbrot (~500ms JS → ~188ms WASM), a chess bitboard search (~15s → ~1s), and HDR Histogram (~7M ops/s → ~28M ops/s). Limitations are that generated WASM has no DOM or network access, runs synchronously with no JS garbage collector integration, and requires manual memory/GC tradeoffs.
