1. 5 Benefits of AngularJS
Heard a lot about Angular.js, but wondering if it will be a right choice for your
web app? Becoming a preferred javascript framework, amidst a group of
frameworks, requires a significant potential. The added functionality which is
not covered by other framework makes Angular.js a hot shot tool for making
web applications.
Let's have a look at the benefits offered by Angular.js, in order to evaluate its
likelihood for your next web app.
● Data Binding
Data binding tops the list of benefits offered by Angular.js. It is the automatic
synchronization of data between the model and the view components. Data

2. binding in Angular.js makes the model the single-source-of-truth. A
single-source-of-truth refers to a practice where the structuring of the
information models and associated schemata is done in a way that every data
element is stored exactly once. Any possible linkage to the data element
happens by reference only.
In two-way data binding an update made to a data element doesn’t needs to
be manually reflected to the entire system. It makes the view a projection of
the model. That means any change made in model gets reflected on its own in
the view and vice versa.
Data binding has its own advantages like:
a. Simplification of the programming model.
b. Easy testability of controller. Because controller is separated from the view
its testing becomes easy in isolation without the view and related browser
dependency.
c. Reduction in the amount of boilerplate code which is meant to keep the
model and view in sync. Developers don’t need to write code that syncs the
model with the view and view with the model.
● Directives
Directives is element or attribute that helps represent a reusable DOM
component. Angular.js has built-in directives like ngClass, ngModel and
ngBind. The directives are used for commanding the HTML compiler to attach

3. a specific behavior to a particular DOM element. They can also be used to
transform the DOM element. In Angular.js one can include additional
functionality by making use of directives.
Angular.js enables developers to invent one’s own HTML elements that cuts
the need to manipulate the DOM. Only things required to be done is assigning
of attributes to elements so as to get a particular functionality.
● Declarative UI
Angular.js uses HTML for templating. It is a declarative language known for
its innate intuitiveness and easy reorganization. The templates contains
Angular-specific attributes and elements like directives, markup, filter and
form controls. Addition of tools like directives and filters adds clarity to the UI.
Having a declarative user interface makes things easy to understand and
manipulate. For designer who are not programmers, learning markup
becomes way more easier than programming. Use of HTML allows
developers and designers to work at the same time. One can use declarative
biding syntax so as to tie different UI components with data models and
designers can create UI. By declaring one’s UI and placing the markup directly
in HTML, one gets to separate presentation logic from the imperative logic.
Declarative UI also helps in reducing the side-effects which may pop out when
one changes something. The side effect is reduced by declaration of the

4. binding at the source and allowing the data binding to decouple the
dependency on the idea from the presentation of the idea.
● Dependency Injection
Dependency injection permeates the framework of Angular.js. Dependency
injection means allocating an instance variable to a object. It is a software
design pattern that transacts with the way components get hold of its
dependencies. With dependency injection it is easy to develop,test and
understand an application.
Dependency injector system is responsible for creation of components,
resolving their dependencies and supplying them to other components as
requested.
● DOM
Use of DOM as input, over the strings separates Angular.js from other
frameworks. Using the DOM lets the developer extend the directive vocabulary
and also build one’s own directives.The abstraction of DOM manipulations
lets the UI designers to focus single-mindedly on the view without confusion.
Usually it is the view that modifies and manipulates the DOM to add behavior.
But in Angular.js DOM manipulation should happen inside the directives only.
With Angular.js the view is seen as just another HTML page for data.

5. The important fact to be known is that Angular.js never manipulates the
templates as strings. As told earlier the templating is done in plain HTML
which are parsed by the browser into the DOM. That means the input to
Angular.js is browser DOM and not an HTML string.
Web app development becomes way more easy if the developers don’t have
to worry about DOM manipulation. DOM becomes the input to the Angular.js
compiler. It is the directives that are responsible for setting up the
data-binding for the application view.
The above mentioned 5 benefits make Angular.js worth a try.
Though you may have heard Angular.js users crib about its initial learning
hurdles and temporary slowdown, still the long term benefits make it worth
the try. However, the time spent in figuring out the framework is justified as
solves the problems encountered in other software architectures.
Angular.js is worth your time.
