@name Developer Guide: Scopes: Working With Angular Scopes
@description

When you use {@link api/angular.directive.ng:autobind ng:autobind} to bootstrap your application,
angular creates the root scope automatically for you. If you need more control over the
bootstrapping process, or if you need to create a root scope for a test, you can do so using the
{@link api/angular.scope angular.scope()} API.

Here is a simple code snippet that demonstrates how to create a scope object, assign model
properties to it, and register listeners to watch for changes to the model properties:

<pre>
var scope = angular.scope();
scope.salutation = 'Hello';
scope.name = 'World';

// Verify that greeting is undefined
expect(scope.greeting).toEqual(undefined);

// Set up the watcher...
scope.$watch('name', function(){
// when 'name' changes, set 'greeting'...
this.greeting = this.salutation + ' ' + this.name + '!';
}
);

// verify that 'greeting' was set...
expect(scope.greeting).toEqual('Hello World!');

// 'name' changed!
scope.name = 'Misko';

// scope.$eval() will propagate the change to listeners
expect(scope.greeting).toEqual('Hello World!');

scope.$eval();
// verify that '$eval' propagated the change
expect(scope.greeting).toEqual('Hello Misko!');
</pre>
