Based on details provided a before update BR like this should work.

var myArray = ['NA', 'NA', 'NA'];

if (u_case_id_1 != '') {
myArray[0] = u_case_id_1;
}
if (u_case_id_2 != '') {
myArray[1] = u_case_id_2;
}
if (u_case_id_3 != '') {
myArray[2] = u_case_id_3;
}

current.u_connect_case_ids = myArray.toString();

//Note edited syntax error

Updated the script as below and it worked

function executeRule(current, previous /*null when async*/) {

    // Add your code here

    var myArray = [];

gs.info("case"+current.u_caseid_1);

if (current.u_caseid_1 != '') {

myArray[0] = current.u_caseid_1;

}

if (current.u_caseid_2 != '') {

myArray[1] = current.u_caseid_2;

}

if (current.u_caseid_3 != '') {

myArray[2] = current.u_caseid_3;

}

current.connect_case_ids_2 = myArray.toString();

gs.info("array"+myArray+":"+current.connect_case_ids_2);
