title: How to access nested data in json string in typescript
body: <p>I have this json structure an can't find a way to access the data values(data1, data2 and date), i'd like to have those values in an array than i can sort by date:</p>
  
  <pre><code>{
  "07" : {
    "07" : {
      "data1" : "-1",
      "data2" : "test",
      "date" : "1995-07-07"
    },
    "08" : {
      "data1" : "1",
      "data2" : "test",
      "date" : "1995-07-08"
    },
    "09" : {
      "data1" : "-1",
      "data2" : "test",
      "date" : "1995-07-09"
    },
    "10" : {
      "data1" : "-1",
      "data2" : "test",
      "date" : "1995-07-10"
    }
  },
  "08" : {
    "07" : {
      "data1" : "1",
      "data2" : "test",
      "date" : "1995-08-07"
    },
    "08" : {
      "data1" : "1",
      "data2" : "test",
      "date" : "1995-08-08"
    },
    "09" : {
      "data1" : "1",
      "data2" : "test",
      "date" : "1995-08-09"
    }
  }
  }
  </code></pre>
  
  <p>Because my keys aren't defined as constant i don't know what they'll be in advance.</p>
