Description: Pipes in Angular are tools that allow data transformation for presentation in application templates. Their main function is to facilitate the manipulation and formatting of data in a simple and efficient manner, enabling developers to apply transformations to the data displayed in the user interface. Pipes can be used to format dates, numbers, currencies, and also to perform more complex operations such as filtering lists or transforming text strings. They integrate seamlessly into the Angular framework, allowing developers to focus on application logic without worrying about data presentation. Additionally, pipes are highly reusable and can be customized, giving them great flexibility and power in web application development. In summary, pipes are an essential feature of Angular that enhances code readability and maintainability while optimizing the end-user experience by presenting data clearly and attractively.
