How to split a number of Array to number of array list with customize size?

This code snippet is an example for splitting an array into sub-arrays (for now, embedded in a dictionary) where you can set the desired "chunk" size (the length of the resulting sub-lists) by changing the value of local!neListChunkSize.

a!localVariables(
  local!list: {11, 22, 33, 44, 55, 66},
  
  local!newListChunkSize: 2,
  local!newListLength: tointeger(ceiling(length(local!list) / local!newListChunkSize)),
  
  a!forEach(
    enumerate(local!newListLength),
    {
      chunk: fv!item,
      subList: {
        local!list[fv!index + fv!item],
        local!list[fv!index + fv!item + 1]
      }
    }
  )
)

Try this example, where local!array is your initial list of integers, and local!childArrayLength is your desired size for the nested arrays:

a!localVariables(
  local!array: {10,20,30,40,50,60,70,80,90,100},
  local!childArrayLength: 2,
  local!finalSize: ceiling(count(local!array)/local!childArrayLength),
  
  a!forEach(
    items: 1+enumerate(local!finalSize),
    expression: {
      reject(
        fn!isnull,
        index(
          local!array,
          if(fv!isFirst,fv!item,fv!item*local!childArrayLength-local!childArrayLength+1)+enumerate(local!childArrayLength),
          null
        )
      )
    }
  )
)

great minds think alike, i guess ;-)

Mike, 

Actually I have already adapted a solution which you post in another question form.

It is working perfertly, thanks!

This is also works! thanks Chris

Was going to say! ;)
