AngularJS Function, difference between parameter with and without '$'

Question

What is the difference between

$scope.firstFunction = function($parameter) {
   //Any code
};

and

$scope.secondFunction = function(parameter) {
  //Any code
}

Thanks.

There is no difference, just a naming convetion. Also built-in Angular modules are prefixed with '$' sign. — Flasz

You need to be a little more specific as to what those parameters actually are. Do both versions of this code actually work? Usually anything prefixed with $ is coming from angular such as $scope, $stateProvider so it SHOULD matter unless something is horribly misconfigurated. — Eugen Timm

Nothing but the name of parameter?

The only place in Angular, where parameters prepended with a $ matters, are where the Dependency Injector works. For instance in Controllers, Services, Directives etc..
