AngularJS is a JS-based open-source front-end web framework. It is a JS framework developed by Google. It eases the development of dynamic SPAs.

It provides a structured framework for building client-side apps. It aims to simplify the process of creating interactive and responsive web pages.

It provides functionalities such as two-way data binding, dependency injection, and modular development.

It offers several benefits, particularly in creating dynamic and responsive web applications.

Two-way Data Binding: It facilitates seamless synchronization between the model and the view.
Modularity and Reusability: The framework encourages the development of modular and reusable code.
Dependency Injection: AngularJS employs dependency injection, enabling efficient management and injection of dependencies.
Directives: It allows developers to create custom HTML tags, attributes, classes, or comments. It enhances the functionality and behavior of HTML elements.
MVC Architecture: AngularJS follows the Model-View-Controller (MVC) architectural pattern.
Testing Support: AngularJS has a built-in support for testing. This makes it easier for developers to conduct unit tests and end-to-end tests.
Single Page Applications: It facilitates the development of SPAs. It is a single HTML page updated as the user interacts with the application.
Community and Documentation: It benefits from a large and active community. It provides extensive documentation, tutorials, and resources.
Wide Range of Tools and Libraries: It integrates with various tools and libraries. It then enhances its capabilities. Tools like Angular CLI simplify project setup and maintenance.
Security Features: It incorporates security features. Those features are such as data sanitization and protection against common web vulnerabilities.

Several key features of angularJs that enhance web development:

1. Data Binding:

Two-Way Data Binding

2. Dependency Injection:

Inversion of Control (IoC)

3. Directives:

Custom HTML Tags and Attributes

4.MVC (Model-View-Controller) Architecture:

Structured Code

5. Services:

Reusable Business Logic

6. Routing:

Single Page Applications (SPAs)

Tips for Getting Started with AngularJS:

Development Environment: Install Node.js and npm.
IDE Choice: Consider using popular IDEs like VS Code for enhanced development features.
Basic Concepts: Focus on understanding AngularJS concepts. Those concepts are two-way data binding, directives, and dependency injection.
Hands-On Practice: Apply your knowledge by building small projects to reinforce learning.

Components of AngularJS:

Modules: Modularize your application using AngularJS modules to organize code and manage dependencies.
Controllers: Controllers handle the application logic, connecting the model and the view.
Services: Services help code reuse by providing shared functionality throughout the application.
Directives: Directives extend HTML with custom elements and attributes. It enables the creation of reusable components.
Filters: Filters format data for display, enhancing the presentation layer.

In conclusion, AngularJS plays a pivotal role in modern web development. It offers a robust framework for building dynamic and efficient applications.

        $scope.template = $scope.templates[1];
        $scope.isEditing = true;
        $scope.buttonText = 'Go back';
      } else {
        alert('you don\'t have permission to edit');
      }
    }
  }
});

Instructions

Follow the steps carefully to get the output easily.

Install Visual Studio Code IDE on your computer.
Create a new HTML file.
Copy the code using the 'Copy' button and create an HTML tag then paste the code inside the tag into that HTML file.
Copy the controller.js code and paste in the JS file created.
Create a script tag inside the body tag Then keep the function lines inside the script tag(refer to preview as well).
Save and run the HTML file directly from the file location to generate the output.

FAQ

1. What is the purpose and structure of an AngularJS Sample Application?

Its purpose is to showcase how it builds dynamic and interactive web applications. The structure includes components, controllers, services, and directives. These prove key concepts of the framework.

2. How does following a style guide benefit developers working with AngularJS?

Following a style guide in AngularJS benefits developers by providing consistent coding practices. It improves code readability and facilitates collaboration. It ensures a unified approach across the development team. It makes the codebase more maintainable and scalable.

3. What other web side server technologies to use with AngularJS?

Web server technologies with AngularJS include Node.js, and Express.js. It is also used in Java with Spring framework. These technologies help serve and handle backend logic and API requests. It handles data interactions in conjunction with the AngularJS front end.

4. What is the role of an HTML file in an AngularJS application?

In this, the HTML file acts as the user interface. It is where Angular directives bind data. It is also used to manage behavior and create a dynamic experience. It serves as the template that Angular uses to render the views and display the app's content.

5. How does the ng-include directive enhance code organization in AngularJS?

It allows the inclusion of external HTML files within a main HTML file. This helps improve code organization. It breaks down large templates into smaller and reusable components. It promotes modularity and maintainability. This makes it easier to manage and update specific parts of the application.
