What does the DataWeave language primarily do in MuleSoft?

DataWeave is a powerful data transformation language used within MuleSoft to seamlessly convert and manipulate data between various formats. Its primary function is to facilitate data transformation processes, such as converting data from XML to JSON, CSV to Java objects, or any other format that might be required when integrating different systems or applications.

The strength of DataWeave lies in its ability to handle complex data transformations with ease, allowing developers to express data transformation logic concisely and readably. The language provides a rich set of functions and operators, enabling users to filter, map, and aggregate data effectively.

In the context of the options provided, while building APIs, managing database connections, and monitoring application performance are crucial tasks in MuleSoft, they are not the focus of DataWeave. Instead, DataWeave's specialization in transforming data makes it an essential tool for data integration within Mule applications.
