I tried to solved a problem for two day. And I was about to give up. I went and watched a movie with all my frustration. As I was checking on devRant while watching . I decided to google again using my phone this time. Immediately I got an idea and back to my computer. Three minutes and I was done with a problem that took me 2day's. All was because I was using RC5 in angular 2 and the module I was using is RC1 angular 2 and they had not indicated the change in the documention 😢😢😢
