This year web development gets a whole lot better thanks to the incredible power of Web Components. In this talk, we'll use polyfills to help you realize tomorrow's web platform today. Learn how to build your own custom tags with true encapsulation that are easily shareable and even extend native browser tags. We'll talk about shadow DOM, custom elements, declarative data/event binding, touch input, smooth animations, and how you can combine them to create awesome apps.
