What’s new in ES6 for Web Devs
summary
ECMAScript 6 targets mid‑2015 ratification and delivers concrete changes: let and const fix hoisting by adding block scoping; destructuring enables swaps and defaults for parameters; import/export modules standardize async module loading plus System.import for dynamic maps to CDNs; classes use extends constructor super static get/set; function star and yield build generators that produce iterators and power frameworks like koa to eliminate callbacks; toolchain includes --harmony, Chrome/Firefox flags, Traceur/Babel and Continuum; IE11/Spartan claim the most complete support.
