What happens when you use the validation module without throwing an error?

• A. Validation operations can be used directly inside DataWeave code
• B. The operation returns a boolean value and can still throw an error
• C. Validation operations require a dedicated validation scope
• D. The operation returns true if valid or false if invalid and does not throw

Answer: (D)

The main idea is that the validation check can tell you simply whether something is valid without raising an error. The best choice describes a non-throwing behavior that yields a boolean: true if valid, false if invalid, and no exception is thrown. This lets you control the flow with a straightforward condition—you can branch or handle invalid input without dealing with exceptions. For example, you can do if validation passes, continue with the transform; otherwise, handle or report the issue. The other statements either imply throwing, or imply different usage patterns (like needing a special scope) that aren’t necessary when you just need a boolean validity result.
