Initialize Constant Using ng-init Variables in AngularJs
Question
I am working with AngularJs and I am initializing a variable in the ng-init of that model.
<body ng-init="allowedState=2" ng-controller="amCtrl">
</body>
Now what I want is to declare a constant using this variable which will then be shared within the app.
angular.module('amModule').constant('temp', ?)
I am trying to figure this out and I am now wondering if it's even possible?

Using ng-init;
ng-init="loader(); firstName = 'John'"
It's better not to use the ng-init instead use below methods;
You can constants or values for initializing variables; Official angular doc link
Example: With Constant:
var app = angular.module('myApp', []);
app.constant('appName', 'Application Name');
app.controller('TestCtrl', ['appName', function TestCtrl(appName) {
console.log(appName);
}]);
With Values:
var app = angular.module('myApp', []);
app.value('usersOnline', 0);
app.controller('TestCtrl', ['usersOnline', function TestCtrl(usersOnline) {
console.log(usersOnline);
usersOnline = 15;
console.log(usersOnline);
}]);
Also, using service is good solution; Using rootScope and service method
