ECMAScript most famous dialect is JavaScript, and the coming version is ECMAScript 6 (ES6). Browsers already started supporting some of its features. JS programmers need to start learning about the coming changes. The presentation will show some of ES6 most useful features like classes, block scope, collections, proxies, arrow functions, iterators, generators, comprehensions, and modules. We will concentrate on the practical aspects of the changes. The session will be interactive, includes many code examples, and will encourage audience participation.
