Angular offers advantages such as two-way data binding, dependency injection, and modular architecture.

• Two-way data binding allows automatic synchronization of data between the model and the view, reducing the need for manual DOM manipulation.

• Dependency injection helps manage dependencies and promotes code reusability by allowing components to be easily injected with their dependencies.

• Modular architecture enables deve...read more

ngModel is a directive in AngularJS that binds the value of HTML controls to application data.

• ngModel is used for two-way data binding in AngularJS.

• It can be used with input, select, textarea, and custom form controls.

• Example:

Struts is a framework for building Java web applications based on the Model-View-Controller (MVC) design pattern.

• Struts framework is based on MVC architecture

• It uses ActionServlet as the controller

• Struts configuration is done using XML files like struts-config.xml

• It provides built-in support for form validation and error handling

• Struts actions are mapped to URLs in struts-config.xml

Dependency Injection in Spring is a design pattern where objects are passed their dependencies rather than creating them internally.

• In Spring, dependencies are injected into a class through constructor injection, setter injection, or field injection.

• This helps in achieving loose coupling between classes and makes the code more testable and maintainable.

• Example: @Autowired annotation in Spring is used for dependency inj

Async/await is a feature in programming that allows asynchronous code to be written in a synchronous manner.

• Async/await is a way to write asynchronous code in a more synchronous style.

• It is used in languages like JavaScript to handle asynchronous operations.

• Async functions return a Promise, which allows them to be awaited.

• Await keyword is used to pause the execution of an async function until a Promise is settled.

Implementing CI/CD involves automating the process of integrating code changes and deploying them to production.

• Set up a version control system like Git to track changes

• Use a continuous integration tool like Jenkins to automatically build and test code

• Implement automated testing to ensure code quality

• Use a continuous deployment tool like Ansible or Docker to deploy code changes

• Integrate monitoring and alerting to track
