How to set/get value in associative array in multidimensional (2D) array in JavaScript

var properties = {
  "isBold": false,
  "isItalic": false,
  "isUnderline": false
};

// Creation of 2D array, 6x6
var listOfProperties = new Array(6);
for (var i = 0; i < listOfProperties.length; i++) {
  listOfProperties[i] = new Array(6);
}

// Population of listOfProperties with properties
for (var row = 0; row < listOfProperties.length; row++) {
  for (var col = 0; col < listOfProperties.length; col++) {
    listOfProperties[row][col] = properties;
  }
}

var property = listOfProperties[2][2];
property.isBold = true; // I would like to populate property isBold
console.log("property > " + property.isBold);

var property = listOfProperties[0][0];
property.isBold = false;
console.log("property > " + property.isBold);

var property = listOfProperties[2][2];
console.log("property > " + property.isBold);
