What is the best way to create a multidimensional array where each sub-array contains a different type of data

When working with a multidimensional array where each element has the same type, declaring it is straightforward: string[][].

But what about when each array is different?

function create3DArray(arg): // <----???
{ firstArray: string[] = [] 
  secondArray: number[] = [] 
  thirdArray: CustomType[] = [] 
  return [firstArray, secondArray, thirdArray] 
} 

I have checked out resources like typescript multidimensional array with different types, but I'm still unsure of how to proceed.

Answer №1

When searching for a tuple, you'll find that it's essentially an ordered collection with a fixed size, as illustrated by the following example:

function generate2DList(input):[string[], number[], CustomObject[]] {}
