 The document begins with brief overview of the AngularJS framework. The overview explains the main AngularJS components - directives, filters, controllers, services, scope. The second section lists and describes different design and architectural patterns, which are implemented inside the framework. The patterns are grouped by the AngularJS component they are used in. If some patterns are used inside multiple components it will be explicitly mentioned.
 
-The last section contains a few architectural patterns, which are commonly used inside most of the single-page applications build with AngularJS.

 ## AngularJS overview
 
-AngularJS is JavaScript framework developed by Google. It intends to provide solid base for the development of CRUD Single-Page Applications (SPA).
-SPA is web application, which once loaded, does not require full page reload when the user performs any actions with it. This means that all application resources (data, templates, scripts, styles) should be loaded with the initial request or better - the information and resources should be loaded on demand.
-Since most of the CRUD applications has common characteristics and requirements, AngularJS intends to provide the optimal set of them out-of-the-box. Few important features of AngularJS are:

 ### Scope
 
-In AngularJS scope is JavaScript object, which is exposed to the partials. The scope could contains different properties - primitives, objects or methods. All methods attached to the scope could be invoked by evaluation of AngularJS expression inside the partials associated with the given scope or direct call of the method by any component, which keeps reference to the scope. By using appropriate *directives*, the data attached to the scope could be binded to the view in such way that each change in the partial will reflect a scope property and each change of a scope property will reflect the partial.

 Another important characteristics of the scopes of any AngularJS application is that they are connected into a prototypical chain (except scopes, which are explicitly stated as *isolated*). This way any child scope will be able to invoke methods of its parents since they are properties of its direct or indirect prototype.

 The filters in AngularJS are responsible for encapsulating logic required for formatting data. Usually filters are used inside the partials but they are also accessible in the controllers, directives, *services* and other filters through Dependency Injection.
