What does the DataWeave language do?

DataWeave is a powerful data transformation language used within MuleSoft. Its primary function is to enable developers to transform data between various formats, such as converting JSON to XML, CSV to Java objects, or even more complex data structures. This capability is essential in integration scenarios where systems communicate using different data formats.

For instance, when an application needs to send data to a third-party service that expects a specific format, DataWeave can be employed to reshape and transform that data accordingly before it is sent. The flexibility and expressiveness of the DataWeave language allow developers to easily manipulate and structure the data as needed, making it a fundamental tool in building effective MuleSoft applications.

In contrast to the other options, DataWeave does not monitor system performance, manage API throttling, or generate deployment scripts. Each of these functions is addressed through other components or tools within the MuleSoft ecosystem, reinforcing the unique role that DataWeave plays in data transformation.
