create an array of objects from a JSON object (useful for harpjs _data.json)

JSON obj to Array

var dataJson = {},
    dataArray = [];

// assuming a JSON structure like this:

dataJson = {
  "key1": {
    "prop1": "val1",
    "prop2": "val2"
  },
  "key1": {
    "prop1": "val3",
    "prop2": "val4"
  }
}

for (var key in dataJson) {
	if (!dataJson.hasOwnProperty(key)) {
		//The current property is not a direct property of p
		continue;
    }
	dataArray.push(dataJson[key]);	
}

console.log(dataArray[1]);
