Angular

Q: What is Angular?

A: Angular is a popular open-source JavaScript framework developed by Google for building web applications. It is a complete rewrite of AngularJS and is often referred to as just "Angular" or "Angular 2+".

Q: What is a component in Angular?

A: A component is a fundamental building block in an Angular application. It is a reusable piece of UI that encapsulates data and behavior. Components have a template that defines the HTML for the UI, and a class that defines the behavior and data for the component.

Q: What is the difference between a module and a component in Angular?

A: A module is a container for related code such as components, directives, services, and pipes. It is used to organize an Angular application into smaller, reusable pieces. A component is a UI element that encapsulates data and behavior.

Q: What is dependency injection in Angular?

A: Dependency injection is a design pattern used in Angular that allows components and services to have their dependencies provided by an external source rather than creating them themselves. This makes it easier to write and test code, and promotes modularity and reusability.

Q: What is a directive in Angular?

A: A directive is a way to attach behavior to elements in the DOM. There are three types of directives in Angular: component directives, structural directives, and attribute directives. Component directives are used to create new components, structural directives are used to conditionally render elements in the DOM, and attribute directives are used to change the behavior or appearance of an element.

Q: What is a service in Angular?

A: A service is a reusable piece of code that provides functionality to multiple parts of an Angular application. Services can be used to share data between components, encapsulate complex business logic, and interact with external APIs.

Q: What is the Angular CLI?

A: The Angular CLI (Command Line Interface) is a tool that makes it easy to create and manage Angular projects. It provides a set of commands for generating components, services, and other files, as well as building, testing, and deploying the application.

Q: What is lazy loading in Angular?

A: Lazy loading is a technique used in Angular to delay the loading of certain parts of an application until they are needed. This can improve the performance of an application by reducing the amount of initial code that needs to be loaded.

Q: What is a resolver in Angular?

A: A resolver is a service in Angular that is used to resolve data before a component is displayed. This can be useful when data needs to be fetched from an external API before it can be displayed in the UI.

Q: What is NgZone in Angular?

A: NgZone is a service in Angular that provides a way to run code outside of Angular's zone. This can be useful when dealing with long-running tasks or external libraries that may cause the application to freeze or become unresponsive.
