AngularJS scope and watch

1) $scope.$watch(VAR, CALLBACK)
2) $scope.$apply() - notify about changes
3) AngularJS scopes are organized in a tree structure and a scope can access its ancestor’s variables. Well, this means that $digest() needs to happen on every child scope in every iteration! Internally, this code is a bit messy in AngularJS, but each iteration of the $digest() loop does a depth-first search and performs the watcher check on every child scope. If any child scope is dirty, the loop has to run again!
4) UI is blocked while $digest() is running
5) angular.equals(A, B) - internal angular function for comparing

services and factories in angular explained

Compilation of very-very useful explanations for beginners what are services and factories and what are their key useful details. Credentials go mostly to stackoverflow.com threads.

Keep in mind all providers in AngularJS ( = value, constant, services, factories) are singletons !

If you want your function to be called like a normal function, use factory. If you want your function to be instantiated with the new operator, use service. If you don't know the difference, use factory.
