Create Array with Dynamic Size

What is your use case / what have you tried already?

Hi Mike

In my case, I receive an array with values, but I only want to return an array with 5 percent of the input array, and random values from that input array.
So, my idea was to do: "
local!inputLenght: length(ri!clientsNif),
local!outputLenght: round(local!inputLenght * 0.05, 0),
".
Now, I want to do an a!forEach() that loops *local!outputLenght* times.

All you need to do for that is probably something like this:

 a!forEach(
   enumerate(local!outputLength),
   /* some code here to pick a random member of the original array per the current fv!item being 0 -> local!outputLength-1 */
 )

Hi,

Try using enumerate function, it will create an array using in your case local!outputLenght, then use it in the forEach to do in there whereever you need

local!arrAux: fn!enumerate(local!outputLenght)

Thanks a lot Mike, this is really helpful

Is there a way to create an array with distinct (or unique) values?

Yes, but there's no automated way to do it so you'll need to figure out a way to do it manually.

Thanks Mike, I will try to do it :)
