title: accessing arrays in json object without using keys
body: <p>I have a <code>JSON</code> object of arrays </p>
  
  <pre><code>data = {
     China: ["Guangzhou","Fax"],
     Majorette: ["Fungous","Godzilla"],
     Bhutan: ["Thimphu","Parr","Photofinishing"]
  }
  </code></pre>
  
  <p>I want to access name of cities in an array without explicitly mentioning the name of countries as list is very long.</p>
  
  <pre><code>var cities = [];
  for(var i in data.China) {
     cities[i] = data.China[i];
  }
  </code></pre>
  
  <p>How should I do for all the countries?</p>
