JarCastingangular-component.js
Start using .component() now!
angular-component.js is a ~1kb script that adds component() support in Angular 1.5 to all Angular versions above 1.3, so you can begin using the new method now.
Note: you must include this script straight after angular.js and before your application code to ensure the component() method has been added to the angular.module global.
