AngularJS - "ngRoute vs ui-router"

The ngRoute as well as ui-router, both are used for defining routing in an application. Following are the differences between them:

• The ngRoute module is created by the AngularJS team, while the ui-router is the third party module.
• The ng-route implements the routing based on the url, while the ui-router implements the routing based on the state of the application.
• The ui-router provides everything that the ngRouter module provides along with additional features.
• Nested states & views
• Multiple named views

For more details on to routing please refer ngRoute API reference and ui-router wiki.
