How is the date pipe utilized in Angular to format a date?

1. By using the String method

2. By using the format method

3. By passing the date object directly

4. By using the pipe syntax with format string

The correct answer is: By using the pipe syntax with format string

The date pipe in Angular is a powerful tool used to format dates within templates. By utilizing the pipe syntax along with a format string, developers can display dates in various formats according to localization requirements or user preferences. This syntax allows for a clean and straightforward way to bind date data directly in HTML templates and apply the desired formatting. When using the date pipe, you simply include it in your template like this: `{{ dateValue | date:'formatString' }}`, where `dateValue` is your date object or date string, and `formatString` specifies how you want the date to be presented. For instance, using the format string 'shortDate' would output the date in a concise format, while 'fullDate' would provide a more detailed representation. The other options do not accurately describe how the date pipe functions. The string method and format method do not pertain to the Angular date pipe specifically, and passing the date object directly lacks the context of applying formatting, which is essential to using the date pipe effectively. Thus, the pipe syntax combined with a format string provides the correct approach for formatting dates in Angular.
