In AngularJS, a scope is an object that refers to the application model. It is an execution context for expressions.

In AngularJS, a scope is an object that refers to the application model. It is an execution context for expressions. Scopes are arranged in hierarchical structure which mimic the DOM structure of the application. Scopes can watch expressions and propagate events.

All scopes are children of the top level $rootScope using prototypical inheritance. A new child scope is created every time a directive in the DOM is configured to do so.

Common pitfall: using scalar variables on the scope within directives that create a new child scope (such as ng-if, ng-switch, ng-repeat, ng-include, ...) and not being able to reference them, due to the prototypal nature of JavaScript (own copy of variable is created in the child scope).
