WebAssembly
Near-native performance in the browser and beyond
WebAssembly is a high-value niche skill enabling compute-intensive browser applications. Compile Rust, C++, or Go to Wasm for 10-50x speedup on math/graphics. Used by Figma, AutoCAD, Google Earth. Senior roles command $150-250k. Learning curve: 6-9 months for intermediate competency; advanced component models require systems programming background.
What is WebAssembly
WebAssembly (Wasm) is a binary instruction format that runs at near-native speed in web browsers and increasingly on servers via WASI. It enables running C++, Rust, Go, and other languages in the browser for compute-intensive tasks like video editing, CAD, games, and data processing. Beyond the browser, Wasm is emerging as a universal runtime for serverless functions, plugin systems, and edge computing. Companies like Figma, Google Earth, and AutoCAD use Wasm for performance-critical web features.
