Angular JS. What to do in error case

Angular JS is a web framework based in MVC(Model View Controller). I know, in the web you can find all about Angular, so, What are you here? Well, I have a good tips when angular throw a error and yes the first tip is keep calm, and do any of the followings things:

• Verify that the server is running ( Yes , it is obvious but check it)
• The browser console is our friend, used it when the page not load(Trust me, probably you have an error)
• Always verify the routes and the controller names. If you put a name bad, all will be wrong.
• Verify you server status, in some situation it can save your time, because  your error can be caused for invalid route.
• If you have sure that all the things are correct and angular not working,you can ask for help  a Google or a good friend. Google always have a answer and your friend, maybe too.

1.  -Angular is relatively simple, when you understand the structure.
