Angular.js ReferenceError: $scope is not defined

Question

I have started practicing the basics of Angular.js and was trying some code doing data binding and controllers, and get the error at following code:

http://jsfiddle.net/yy9wM/

$scope.$watch('funding.startingEstimate', computeNeeded);

The error I get in browser console is ReferenceError: $scope is not defined. I have read the related questions to this but didn't help

The problem here is your app isn't even running. jsfiddle can be tricky to with angular.

Here is what it looks like you were trying to do: http://jsfiddle.net/yy9wM/1/

Angular will now bootstrap itself, and be wrapped in the head.

$scope is passed into you controller function CalcController it is not defined outside of that. It represents the scope of that controller, so any properties defined on that scope are available with in the controller just like {{needed}}.

I'd suggest following a tutorial or revisiting some javascript basics as your code shows little understanding of javascript principals.

Good luck.

I prefer jsbin to jsfiddle myself.

JSFiddle can be a funky when it comes to loading Angular. You also had $scope.watch defined outside of your controller.

Here is a working example: http://plnkr.co/edit/EgTH6OThy8or3rPpi0a7?p=preview
