$watch vs $on in angularjs

$watch vs $on in angularjs


The $on is used to listen to each events.

$on also work to push a function into a stack and returns to another function and clean the original functions from that stack.


The angularjs create watch internally.
The watch means that angularjs watches the changes in the variable on the $scope object.

The watches are created using the $scope.$watch() method.

The $ method creates a watch of some variables. 

When you register a watch you need to pass two functions

1. One is value function
2. and other is listener function

for example

$scope.$watch(function() {},function() {});
