Modern JavaScript and CSS for Drupal, no polyfills required

Building frontend code can be difficult when having to support legacy browsers. This session will introduce how the future of frontend tooling currently works in a modern browser. If a project does not support IE11 it opens up the modern web. In this session we will use the modern browser to create an awesome frontend component without any building, transpiling, or polyfills.

In this session we will build a component that covers these topics.
