次の JSON オブジェクト配列でプロパティの値 (「ObjectPropertyTwo」など) をリストするにはどうすればよいでしょうか?

    {
    "KeyOne": [
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
    ],
    "KeyTwo": [
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
    ],
    "KeyThree": [
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        },
        {
            "ObjectPropertyOne": "value",
            "ObjectPropertyTwo": "value",
            "ObjectPropertyThree": "value",
            "ObjectPropertyFour": "value",
        }
    ]
}

どうですか：

for (var key in data) { //data being the object
    for (var i = 0; i < data[key].length; i++) {
        console.log(data[key][i].ObjectPropertyTwo);
    }
}

function listNestedProperties(object, property) {
  return Object.keys(object).reduce(function(memo, key) {
    object[key].forEach(function(o2) {
      memo.push(o2.ObjectPropertyTwo);
    });
    return memo;
  }, []);
}

listNestedProperties(yourObject, 'ObjectPropertyTwo');
// => ["value", "value", "value", "value", "value", "value", "value", "value", "value"]
