$q is a constructor and also it's service in module ng. A service that helps you run functions asynchronously and use their return values (or exceptions) when they are done processing. Please Refer the Following links : https://docs.angularjs.org/api/ng/service/$q?as_q=q$ and https://toddmotto.com/promises-angular-q#when-to-use-q You asked for examples but above two pages you want refer to understand...what answer you want is given in that Links...
