A Polymer 2.x mixin that provides some useful methods for data bindings. See the listing on webcomponents.org for full documentation (You'll need to click on "Show N protected methods" to see them).

Example

<dom-module id="my-element">

        </style>
        
        <template is="dom-if" if="[[_isTruthy(foo)]]">
            foo is: truthy
        </template>
        
        <template is="dom-if" if="[[_isFalsey(foo)]]">
            foo is: falsey
