DataWeave is a MuleSoft expression language for accessing, querying, and transforming data that flows through the Mule application. It is tightly integrated with the Mule runtime engine, which reads the script and expression in our application. It is a powerful template engine that transforms data to and from any kind of format like CSV, JSON, XML, MAP, POJO's, etc.
Dataweave now() function is used to return the current date and time when used inside our application.
