Notes

map map and mapObject functions to iterate through the input

• map to go through the elements in the "books" array.
• mapObject to go through the keys and values in each of the objects of the array and do something For example

%dw 2.0
output application/json
---
items: payload.books map (item, index) -> {
      book: item mapObject (value, key) -> {
      (upper(key)): value
      }
}

the groovy closest equivalent would be

list/object.foreach{ key, value ->
// do something 
}
