Maybe you don't need Rust and WASM to speed up your JS (mrale.ph)

Few weeks ago I noticed a blog post “Oxidizing Source Maps with Rust and WebAssembly” making rounds on Twitter - talking about performance benefits of replacing plain JavaScript in the core of source-map library with a Rust version compiled to WebAssembly.

This post piqued my interest, not because I am a huge on either Rust or WASM, but rather because I am always curious about language features and optimizations missing in pure JavaScript to achieve similar performance characteristics.

So I checked out the library from GitHub and departed on a small performance investigation, which I am documenting here almost verbatim.
