What we can use instead is a function that does something more general, the reduce function. Which returns 3. The accumulator is what stores what is potentially returned from reduce. Continue your development journey with the rest of the tutorials to become a master in DataWeave. Otherwise, set the option to "false". In this tutorial, you will learn how to transform an input Object into an Array with the pluck function. length; i++) byteArray [i] = array [i]; Or the for loop can be replaced with a stream if you want: The module dw::core::Arrays has extra functions that are useful when working with arrays in DataWeave. Convert Array To String In Dataweave 2.0 You can use joinBy Dataweave 2.0 function to convert array to string Example Input: [1,2,3,4,5] Dataweave Expression: %dw 2.0 output application/json --- { "a": payload joinBy ("-") } Result: { "a": "1-2-3-4-5" } Thank you for taking out time to read the above post.

We transform the Object that was generated in Step 1 (with its own internal Arrays) into an Array. In this tutorials, we will be looking into three techniques which objects can be changed in to array using any of these three methods: Object.keys(), Object.values(), and Object.entries() Say we have a cart object defined as follow: Dataweave: Transform Message 1: %dw 2.0 output application/java --- payload.parts.ledger.content Transform Message 2: %dw 2.0 output application/json --- read (payload,"application/json") If a default value is not declared for the accumulator, it uses the first item of the input Array and passes the second item of the input.
