A pipe is a feature in Angular that allows you to transform data in templates.

• Pipes are used to format data before displaying it in the view

• Common built-in pipes include DatePipe, UpperCasePipe, LowerCasePipe

• Custom pipes can be created for specific formatting needs

Services are reusable code that can be shared across components, while components are building blocks of an Angular application.

• Services are used for fetching data from a server, sharing data between components, and encapsulating reusable logic.

• Components are responsible for the UI and user interactions, and can be thought of as custom HTML elements.

• Services are typically singleton instances, while components are instantiated multiple times.

• Components have a template, styles,...read more

Dependency Injection is a design pattern in which a class receives its dependencies from external sources rather than creating them itself.

• Allows for easier testing by injecting mock dependencies

• Promotes reusability and modularity by decoupling components

• Reduces code duplication by centralizing dependency creation

• Example: Angular uses Dependency Injection to provide services to components

Routing is the process of navigating between different pages or views in a web application.

• Routing allows users to move between different parts of a web application without reloading the entire page

• It is implemented using a router module in Angular, which maps URLs to components

• Routes can have parameters that can be passed to components for dynamic content

• Routing can be used to create single-page applications (SPAs) where content is dynamically loaded

Angular provides a robust framework for building dynamic web applications with features like two-way data binding, dependency injection, and routing.

• Two-way data binding simplifies the process of updating the UI based on changes in the data model.

• Dependency injection allows for easier management of dependencies and promotes modular code.

• Angular's routing capabilities enable the creation of single-page applications with multiple views.

• Angular CLI provides a command-line interf...read more
