What is AngularJs

AngularJS is a JavaScript framework for developing high-performance, large-scale, and easy maintenance web applications. It is a fantastic framework for designing single-phase web applications and business applications. The open-source AngularJS framework maintains and update by Google and comes under Apache 2.0 version license.

 

Essential Features

The primary characteristics of AngularJS are as follows:

 

Feature

Description

Data binding

The synchronization of data between model and display components.

Scope

These are model-referencing items. They serve as a link between the controller and the view.

Controller

These are JavaScript functions that are scope-bound.

Services

AngularJS provides various built-in services such as $http for XMLHttpRequests. 

Filters

This function selects a subset of array elements and returns a new array.

Directives

AngularJS directives are labels placed on DOM elements such as elements, attributes, and more. For example, ngBind and ngModel.

Templates

These are the rendered views that contain information from the model and controller. The template uses a single file or numerous partials on a single page.

Routing

It is the idea of shifting perspectives.

Model View Anything

MVC is a web development design pattern for separating an application into three discrete. It is AngularJS Model, View, and Controller components. This component comes with its responsibilities.

Deep Linking

Deep linking enables bookmarking by encoding the state of an application in the URL. The program restores to the same condition from the URL.

Injection of Dependencies

The built-in dependency injection mechanism of AngularJS facilitates applications' creation, comprehension, and testing.

 

Benefits of AngularJS

Numerous JavaScript frameworks exist for developing online apps. Therefore, the question of why to utilize Angular JS is legitimate.

AngularJS has the following benefits over other JavaScript frameworks:

  • Injecting Dependency pattern: Dependency Injection is a design pattern in which components are provided their dependencies instead of having them hard-coded into the component.

  • Two-way data binding function: AngularJS establishes bidirectional data binding between the select element and the orderProp model. orderProp is then passed to the orderBy filter as its input.

  • Easy Testing: AngularJS builts to be testable from the very beginning. Therefore, verifying any components via unit testing and end-to-end testing is straightforward.

  • Model View Controller (MVC) structure: In Angular JS, it is straightforward to construct MVC-compliant applications. Simply divide your application's source code into Model, View, and Controller components.

  • Various Functions: AngularJS framework provides several functions such as Directives, filters, modules, routes, etc.

 

Advantages of Angulat JS

 

Drawback of AngularJS

AngularJS has several advantages, but there are also a few drawbacks.

  • Not Secure application: AngularJS applications are not secure due to their JavaScript-only framework. Application security requires server-side authentication and permission.

  • Not degradable function: If a user disables JavaScript in your application, only the basic page would be viewable.

 

Use of AngularJS

AngularJS works in several digital sectors to create web applications. Here is an available list of AngularJS sectors.

  • Travel web Applications: This application creates for traveling with booking, staying, and providing essential information.

  • Weather forecasting Application: This application informs current weather. It provides information about upcoming natural calamities and sudden changes in the environment.
