Describe how to extract meaningful error messages from the HTTP response body in Angular when an error occurs.

When an HTTP request results in an error, the server often sends a response body containing details about the error (e.g., validation errors). You can access the error body using the `error` property of the `HttpErrorResponse` object. Ensure you inspect the `error` property, and if it's a JSON object, parse its contents to extract relevant error messages. The format of the error body depends on your backend API. Use different types of conditional statements or switch statements to parse and extract information based on the format of the error response.
