Oxidizing Source Maps with Rust and WebAssembly
A detailed look at how we replaced the most performance-sensitive portions of the
source-mapJavaScript Library’s source map parser with Rust code that is compiled to WebAssembly. The results: The WebAssembly is up to 5.89 times faster than the JavaScript implementation on realistic benchmarks operating on real world source maps! Additionally, performance is also more consistent: relative standard deviations decreased. We hope that, by sharing our experience, we inspire others rewrite performance-sensitive JavaScript in Rust via WebAssembly.
