wanna fetch random number?

step 1: generate list of possible returns (this can be an enumerated list or any other list, for the sake of flexibility)

step 2: create a "wrapper object" list where each list is assigned a random sort value

step 3: sort by the sort value, essentially randomizing the list

step 4: grab the first N results from the randomized list and return [note: paging lets us do this more easily]

a!localVariables(
  local!myValues: enumerate(100)+1,  /* can be any list */
  local!numberToReturn: 30,  /* can be whatever you want */
  
  local!sortableObjectList: a!forEach(
    local!myValues,
    a!map(
      originalIndex: fv!index,
      sortValue: rand()*10,  /* resolves as decimal between 0 and 10, for readability */
      value: fv!item
    )
  ),
  
  local!sortedPage: todatasubset(
    arrayToPage: local!sortableObjectList,
    pagingConfiguration: a!pagingInfo(
      startIndex: 1,
      batchSize: local!numberToReturn,
      sort: a!sortInfo(
        field: "sortValue",
        ascending: true()
      )
    )
  ),
  
  local!sortedPage.data.value
)

That's a nice solution :-)

That's a nice solution :-)

thanks!  i believe someone else originally gave me the idea for the assignment of a randomized sort index to the original array - maybe you (not sure, sorry).  Credit where credit is due if it were possible, but I just re-typed it in this case from memory.  I think i'll save it as a tool going forward though, it seems potentially useful.
