Want es.next Now? Traceur Your Way Back to ES5 and Feel the Harmony
summary
Shows that you can write ES6 today but must transpile and polyfill to run broadly: uses Babel, in-browser demo and a gulp build that bundles with browserify + babelify, live-reloads via BrowserSync, and runs unit tests through Karma by preprocessing ES6 into ES5. Demonstrates Node options (babel-node, io.js) and pitfalls like array.from missing without a polyfill and classes not supported in some nightly Firefox builds. Workflow works but requires careful module and feature configuration and lots of testing.
