Advantages and Disadvantages of AngularJS

Key Features of AngularJS

Two-way data-binding

Two way data binding means automatic synchronization of data between the model and view components. Whenever the model changes,angular will cause the view to automatically update leading to no explicit DOM (Document Object Model) manipulation and vice versa. READ MORE

Minimal Code

AngularJS reduces the number of LOCs when compared to Javascript/JQuery.

Directives

At a high level, directives are markers on a DOM element (such as an attribute, element name, comment or CSS class) which attach a special behavior to that DOM element (e.g. via event listeners), or even to transform the DOM element and its children.

Client side MVC framework

In Server side MVC framework, based on incoming client request the Controller existing at the server side retrieves the model and prepares the view which is sent back as a response to the client. While in Angularjs the client gets the response from the server as JSON data. The client browser parses the data to generate the model, creates the view templates and renders the page.

Dependency Injection

Dependency Injection (DI) is a software design pattern that deals with how components get hold of their dependencies. The Angular injector subsystem is responsible for creating components, resolving their dependencies, and providing them to other components as requested. It reduces the load on the backend and helps to create a lighter application.

Filters

A filter formats the value of an expression or transform input to an output for display to the user. They can be used in view templates, controllers or services.It is easy to define your own filter.

Templating

Angular combines the template with information from the model and controller to render the dynamic view that a user sees in the browser.

Deep Linking

Deep linking allows you to encode the state of application in the URL so that it can be bookmarked. The application can then be restored from the URL to the same state.

Reduce the network traffic when compare to use server side scripting language like jsp,asp.

REST.

Integration Test Runner.

Form Validation.

Localization.

Cross browser support and no dependency on any external libraries.

Disadvantages of AngularJS

Client must enable JavaScript in the browser. Memory leak in JavaScript can even cause powerful system to slow down the browser. AngularJS works well only from Internet Explorer 8.0 onwards and doesn't support any older versions.
