📘 What You’ll Learn in Session Four Link to
1) The purpose and power of DataWeave, MuleSoft’s core transformation language
When and how to use key DataWeave functions: map, filter, reduce, groupBy, orderBy, ++, and default
The structure of a DataWeave script (header, delimiter, body) and how to avoid common syntax errors
How to identify and handle data types (arrays, objects, strings, numbers, nulls) to prevent transformation errors
Real-world and exam-style transformation examples, including:
Concatenating name fields
Mapping arrays of objects
Filtering for active entries
Reducing values for totals
Grouping and sorting by fields
Default values for missing data
Joining related data using map + filter
How to write and read lambda expressions in map, filter, and reduce
