Esprima (harmony fork)

Esprima (version 1.1.1-dev-harmony) is a high-performance, standard-compliant ECMAScript parser written in JavaScript. It supports full ES5.1 and experimental ES6/Harmony features (modules, classes, destructuring). Runs in browsers (IE6+) and Node.js (>=0.4.0). Known for being up to 3x faster than UglifyJS v1. This is an unofficial fork with the '-harmony' suffix, indicating pre-release support for ES6. Note: this package may be considered obsolete compared to mainline esprima releases.
