What is the primary function of the 'Transform Message' component in Mule?

The 'Transform Message' component in Mule serves the primary function of altering the format or structure of messages as they pass through the data integration process. This component utilizes DataWeave, a powerful data transformation language, to manipulate and convert data between various formats, such as JSON, XML, CSV, or plain text.

For instance, if an incoming message is in XML format and needs to be converted into JSON for further processing or sending to an API, the 'Transform Message' component allows developers to easily specify the transformation rules. The use of this component ensures that the data being sent to different systems aligns with their expected formats, thus increasing interoperability and easing integration challenges.

This is distinct from other options like sending messages to another system, filtering incoming messages, and encrypting messages. While these are important functions in data integration, they do not encapsulate the primary responsibility of the 'Transform Message' component within Mule.
