Main points:
- DataWeave 2.0 provides mapping capabilities
- Java and DataWeave can achieve the same mappings
- DataWeave mapping function is less verbose than Java
DataWeave map function
The DataWeave 2.0 (Mule 4) map function shares similarities with the map() method from Java’s Stream class.
Mapping is a transformative operation
The idea of mapping is to transform each element of an array and output a new array of transformed elements. An expression is provided that performs the transformation. It is applied to each element in the array and collected into another new array.
