Jazzle

Jazzle is an early-stage, zero-dependency ECMAScript transpiler focused on speed and novel technique implementation (e.g., temporal dead zones, super-bound this). Current version is 0.0.0, which indicates a pre-release or initial development phase. It claims ~2x faster than Babel on early benchmarks. Differentiators include zero dependencies, very fast transpilation, and unique support for certain edge cases like temporal dead zones. However, it is not production-ready and lacks CLI, documentation, and maturity. Not recommended for real projects.
