title: How to loop multidimensional map in javascript
body: <p>I am unable to loop through the multidimensional map, I have a sample map below,
  here known values are its key. i.e 'one', 'two'.. Now how can I find out the inner values of it. I would like to get <strong>a,b</strong> from <strong>one</strong> and <strong>c,d</strong> from <strong>two</strong></p>
  
  <pre><code>{
    one: {
      a: {
        id: '6',
        name: 'abc',
        age: '30',
        place: 'xyz'
      },
      b: {
        id: '7',
        name: 'def',
        age: '31',
        place: 'xyx'
      },
    },
    two: {
      c: {
        id: '8',
        name: 'ghi',
        age: '32',
        place: 'xxz'
      },
      d: {
        id: '9',
        name: 'ghi',
        age: '33',
        place: 'yyx'
      }
    }
  }
  </code></pre>
