What does this JavaScript mean?
<p>I am working on a legacy application and all JS seems mystrious to me.<br>
Here is the few mysterious lines which are loaded before all and I don't have any idea what they are doing.    </p>

<pre><code>var i2b2 = {sdx:{TypeControllers:{},Master:{_sysData:{}}},events:{},hive:{cfg:{},helpers:{},base_classes:{}},h:{}};  
if (undefined==i2b2.hive) { i2b2.hive = {}; }     
i2b2.hive.tempCellsList = [
        { code: "PM",
          forceLoading: true 
        },
        { code: "ONT"   },
        { code: "CRC"   },
        { code: "WORK"},
        { code: "SHRINE"},
        { code: "PLUGINMGR",
           forceLoading: true,
           forceConfigMsg: { params: [] }
        }
    ];
</code></pre>

<p>There are many more <code>var</code> and <code>if</code> statements but they are doing same thing with different variables.<br>
Please help me to solve this mystery.   </p>
