Data binding in Polymer 1.0
https://www.polymer-project.org/1.0/api/#dom-bind
<body>
<template is="dom-bind">
<h1>{{title}}</h1>
<paper-slider value="{{title}}" style="width: 100%"></paper-slider>
</template>
</body>
This took way too long to figure out. I only found out by looking at the Polymer unit tests.
