How to Return String Array in a Mule 4 Function?

Hi i am working on a Migration project from Spring to Mule .

In Java we have small function like

 private String[] getPurpose(loanPurpose){
    String purpose[] = new String[2];
    if ("REFINANCE".equalsIgnoreCase(loanPurpose)) {
        purpose[0] = "Refinance";
        purpose[1] = "Cash-Out";
        return purpose;
    } 
    return null;
}

In Mule i am writing it like below .

fun getPurpose(data) = 
if(upper("PURCHASE") == data) 
// how i can assign the values in string array and return

enter image description here

It should work fine in studio as well. Probably the way the if value is represented could be throwing it off.. Try with the following:

%dw 2.0
output application/json

fun getPurpose(data) = 
if(upper("PURCHASE") == data) (["Refinance", "Cash-Out"]) else if (1 == 2) "abc" else "nothing"
---
getPurpose("PURCHASE")

Output:

[
  "Refinance",
  "Cash-Out"
]

[ "Refinance"," Cash-out"]

Just create the array literal with the strings as the last value of the function. I'n this case the is the value of the true branch of if.
