Angular Interview Practice

Which of the following is a built-in Angular pipe used to format date values?

1. Uppercase

2. Currency

3. Json

4. All of the above

The correct answer is: All of the above

The correct answer indicates that there are several built-in pipes in Angular that can format data, including date values. However, focusing specifically on date formatting, the Angular framework provides a dedicated pipe called "DatePipe," which is specifically designed to format date values into a variety of string formats based on the specified parameters or locale. While options like Uppercase, Currency, and Json are indeed built-in pipes in Angular, they serve different purposes and are not used for date formatting specifically. The Uppercase pipe transforms strings to uppercase letters, the Currency pipe formats numbers as currency, and the Json pipe converts an object into a JSON string. Therefore, the reference to "All of the above" would not be appropriate as a correct answer, as not all these options relate to date formatting. In terms of understanding Angular pipes, they are used within templates to allow developers to easily transform data for display purposes. The DatePipe would be the selection of choice for anyone looking to format date values correctly within an Angular application.
