Well, you didn't exactly ask a question, but I'll answer anyway :) The answer is that you should not use a normal array for this, but rather a map or associative array. Fortunately a plain Javascript object can be used for this:

var numbers = {};

// Variables
var records;
var numbers;
var index;
var output;
var outputMessageOne;
var outputMessageTwo;
var count = 0;

output = document.getElementById('outputDiv');
records = openZipCodeStudyRecordSet();

output.innerHTML = "The unique zip codes are: ";

while (records.readNextRecord()) {

    var zipCode = records.getSampleZipCode();
    numbers[zipCode] = 1; // just picking an arbitrary value
}

for (var zipCode: numbers) {
  output.innerHTML += zip + " ";
}

The reason is that this way you don't need to loop through the existing data for each new input.
