UglifyJS ES6 (Harmony Branch)

UglifyJS is a JavaScript parser, minifier, compressor, and beautifier toolkit. This package (uglify-js-es6) is a temporary release of the harmony branch that adds support for ECMAScript 2015+ (ES6+) syntax. The current stable version is 2.8.9, released as a snapshot from the harmony development branch. Unlike the main uglify-js package which only supports ES5, this fork provides ES6+ minification without requiring additional transpilation steps. The package is unmaintained and meant as a stopgap for environments where git is not available—users should instead install directly from the harmony branch on GitHub.
