Sweet sixteen, but where are the tools?
summary
Zeon is a static JavaScript analyzer built on a handwritten parser that produces two token streams, scope chains, type inference and configurable warnings, and can generate JSDoc, minify, macro/pragma-process and beautify code. It includes a real-time visual profiler and a prototype-instance variable detector. A local benchmark claims 1 MB in 700 ms parsing. The browser demo sometimes fails but core tools—warnings, flow analysis, rewrites and profiling—are implemented and runnable.
