Add comma as a delimiter but not between State and ZIP Code

I have [Address], [City], [State], [Zip] in an array, but any one or more of these may be empty.

I would like to display them on the page with a comma between each key-value pair, but if both State and ZIP are present, they should not get a comma in between!

This is what I have so far:

    var student_address_array = [Address, City, State, Zip]; //Put variables into array
    var student_address_array_cleaned = student_address_array.filter(function(v){return v!==''}); //Remove empty array items
    var student_address = student_address_array_cleaned.join(', '); // Convert array to string with ', ' as the delimiter

But this puts a comma before ZIP code...

Is the only answer RegEx of some sort?

Concatenate State and Zip in to the same element of the array and then join the array by comma:

var student_address_array = [student_info.Address1, student_info.City, (student_info.State + ' ' + student_info.Zip).trim()];
var student_address = student_address_array.join(', ');


var student_info = {
  Address1: 'address1',
  City: 'city',
  State: 'CA',
  Zip: '90210'
};

var student_address_array = [student_info.Address1, student_info.City, (student_info.State + ' ' + student_info.Zip).trim()];
var student_address = student_address_array.join(', ');

console.log(student_address);
