Setup

    e: {
    f: {
    g: {
    h: {

    k: {
    l: {
    m: [1,2,3,4,5]
    }
    }
    }
    }
    }
    }
    }
    }
    }
    }
    }
    }
    };
  
  function loadScript(url, callback)
  {
      // adding the script tag to the head as suggested before
     var head = document.getElementsByTagName('head')[0];
     var script = document.createElement('script');
     script.type = 'text/javascript';
     script.src = url;
  
     // then bind the event to the callback function 
     // there are several events for cross browser compatibility
     script.onreadystatechange = callback;
     script.onload = callback;
  
     // fire the loading
     head.appendChild(script);
  }
