What is Angular 7 and how does it help to develop applications?

Angular is a framework that is used to develop a web application. It is becoming popular due to its unique features and eases to create an application. Angular 7 is an open-source JavaScript framework which is developed by Google. It is completely dependent on HTML and Javascript. The angular Certification course will help in understanding how it is used to convert a static HTML page into a dynamic HTML page. It is used to develop web applications and apps in JavaScript, HTML, and Typescript which is a superset of JavaScript. Angular 7 consists of various elements that together form a tree structure with main and sub-components. Angular training in Hyderabad provides knowledge regarding basic and advanced concepts of Angular 7. 

Angular 7 Tutorials – Prerequisites

To learn angular you can do angular online training. To learn angular 7, one should have the knowledge of the previous version of angular. Previous version of angular can be learned by doing angular online training Various Prerequisites to learn angular 7:

•    Angular2

•    TypeScript

•    HTML

•    CSS

To learn this entire one can take the help of an angular 7 tutorials.

Angular 7 Architecture

Various components are combined together to build an angular application. Angular 7 tutorial is incomplete without its architecture and elements:

1. Modules

It provides a common place to group various elements related to the web application such as directives, components, services, etc.

2. Components

It is a typescript class in which one can create methods and properties as per their requirements and combine with the HTML page to display the content to end user.

3. Templates

It is the user-friendly element of an angular application. A template is the HTML page having content that is being displayed at the user end.

4. Metadata

It is collecting data about data. Decorators are metadata in angular.

5. Data Binding

It is the process of synchronizing data and DOM. Two types of Data Binding are there in Angular 7:

•    Event Binding

•    Property Binding

6. Directives

Directives are used to expand the functionality of the HTML components. There are different types of directives in Angular - Structural Directive, Attribute Directive, and Component Directive.

7. Services

Services are used to reuse the code. The services are created for that code which is common for more than one component.

8. Dependency Injection

It is the pattern of angular design to enhance the efficiency and modularity.

Applications of Angular 7

The practical applications of Angular 7 can be understood by doing Angular certification course. Angular 7 has become one of the most widely used language over the web. Angular 7 serves multiple benefits that invokes user to use it as a framework for their web developments. Following are the some of the applications of Angular 7 for web development:

1. Google Supported Community

Angular comes with Long-Term Support (LTS) provided by Google. The Google team is very confident about the stability of angular. Therefore most of the Google apps use angular platforms.

2. Plain Old JavaScript Object (POJO)

It does not require any ‘getter and setter method’. Every object it uses is a simple old javascript object. It provides javascript functionalities to support the manipulation of an object such as adding or removing properties from the object. Angular heavily used POJO and it helps in learning Angular in an easier manner.

3. Declarative User Interface

Angular uses HTML to define the complex part of an application. Html is a declarative language too. You need not to worry about the flow of the program when it loads. Just define what you want as per the requirement of the application and angular will take care of the rest of things.

4. TypeScript

It is a superset of javascript, which is written in typescript. It ensures high security and is highly object-oriented. If you have developed proper map files during build time, then you can easily restore typescript code in an editor or on a browser.

5. Modular Structure

The development of modular is highly modular and based on components. It organizes different codes into modules whether it is components, directives, pipes or services. By separating the code it makes organizing of functionality simple and easy. It also provides lazy loading, which means loading of an application feature in the background as per the requirements of a user.

6. Consistency in Code

It promotes the readability of code. Code consistency enables a new developer to go through the project. It also improves the productivity of developers. 

7. Multi-platform support – 

Generally, all platforms use angular code without implementing very much change in codes/

There are many angular online training sites that teach angular 7 as well as other versions of angular in detail.
