• Question 71:

  What is output of Dataweave flatten function?

  A. Object
  B. Map
  C. Array
  D. LInkedHashMap
  C. Array

  ---

  Explanation

  Correct answer is Array.

  Flatten turns a set of subarrays (such as [ [1,2,3], [4,5,[6]], [], [null] ]) into a single, flattened array (such as [ 1, 2, 3, 4, 5, [6], null ]). This example defines three arrays of numbers, creates another array containing those three arrays, and then

  uses the flatten function to convert the array of arrays into a single array with all values.

  Source

  %dw 2.0

  output application/json

  var array1 = [1,2,3]

  var array2 = [4,5,6]

  var array3 = [7,8,9]

  var arrayOfArrays = [array1, array2, array3]

  flatten(arrayOfArrays) Output [ 1,2,3,4,5,6,7,8,9 ]
