## <app-localize-behavior>
`app-localize-behavior` is a behavior that wraps the [format.js](http://formatjs.io/) library to
help you internationalize your application. Note that if you're on a browser that
does not natively support the [Intl](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl)
object, you must load the polyfill yourself. An example polyfill can
be found [here](https://github.com/andyearnshaw/Intl.js/).
See: [Documentation](https://www.webcomponents.org/element/@polymer/app-localize-behavior),
[Demo](https://www.webcomponents.org/element/@polymer/app-localize-behavior/demo/demo/index.html).
