I made JS libraries optimized for performance & bundle size.

• mapl: A compiled cross-runtime JS framework.
• stnl: A type definition format optimized for compilation.
• fast-crypt: An efficient crypto library for all runtimes.
• udic: Small, simple dependency injection library.
• ciorent: Lightweight, low-overhead concurrency library.

With some benchmarks to verify their performance.

• startup-size: JS startup time, bundle size and gzipped size benchmark.
• micro: Micro-benchmarks for all JS runtimes and engines.

And low-level things sometimes.

• nuws: Low-overhead, opinionated uWebSockets bindings for Nelua.
