It's a JavaScript JIT compiler. From the info page [1]: Some notable features of Higgs include: - A self-hosted runtime written in extended JavaScript - Lazy/incremental JIT compilation Context-driven versioning of basic blocks - A Foreign Function Interface (FFI) system to interface with C code - An interactive shell (REPL) with access to low-level primitives. - A simple module system and a set of useful libraries. Example usage: higgs --e "var x = 4; x = x + 5; print(x)" or higgs file.js [1] http://pointersgonewild.wordpress.com/higgs/ http://pointersgonewild.wordpress.com/higgs/
