AngularJS is an open-source, and
front-end web application framework JavaScript-based. The main aim of this
language is to simplify both the development and the testing of various
applications by providing a framework for the client-side. AngularJS is a basic
framework for dynamic web apps. It has many features as listed below:
1. MVC
2. User interface with HTML
3. POJO Model
4. Active community on Google
5. Routing
6. Two-way binding
1. Model View Controller (MVC) Framework - MVC is a
software design pattern used for developing web applications. It is made up of
model, view, and controller.
Model: Model is the first level of the MVC pattern responsible for
maintaining data. It has similar primitive data types such as booleans,
numbers, strings or objects. Model is the simplest script without any better
and sorter methods.
View: It is responsible for showing parts of data to the user. The
data presented by them is in a particular format triggered by the controller’s
action.
Controller: It controls the synergy between the Model and the
View. It reacts to user input and accordingly interacts with the data model
objects. The controller receives the input, validates it, and then conducts the
operations.
2. User interface with HTML - Angular JS lets you use HTML as
your template language. It lets you extend HTML's syntax. This way it get to
express the application's components clearly.
3. POJO Model - AngularJS uses Plain Old JavaScript (POJO) objects.
It means you do not need to add extra elements to bind AngularJS along with
additional data sources.
A POJO model also provides natural
and well-planned objects. In POJO Model developers have to create loops of
objects and arrays with the required properties and need to adjust &
reframe it. This makes AngularJS efficient and easy to use.
4. Active community on Google - Since Google maintains AngularJS it
is released under the MIT license and is available for free which you can
download on GitHub. So, any maintenance issues can be resolved because there
are many forums.
5. Routing - Routing is the transition from one view to another.
And the key feature of single page applications. Some of the best examples of
Single Page Applications are - popular platforms like the Chrome app store and
Twitter.
6. Two-way binding - Data binding is the automatic sync of data between
the view and the model. The model indicates the JavaScript variables and the
view indicates the HTML. In fact, in AngularJS, you can easily build any
template which can bind with different components and with different models.
With two-way data binding, the
application's delivering layer becomes very simple. As a result, the UI is
clean. And, also complex data manipulations and calculations can be done with
ease.
Further, AngularJS takes another
approach as compared to others.
It
attempts to minimize the impedance mismatch between document-centric HTML and
an application need by creating new HTML constructs.
