How to add another object to this object
<p>I am new to JSON and Here is my First JSON Object  </p>

<pre><code>var First = {
              "a" : [{}]
            };
</code></pre>

<p>I want to add the below object to "a" in "First"</p>

<pre><code>var a = {"1":"One","2":"Two"};
</code></pre>

<p>I have tried below code  </p>

<pre><code>First.a[First.a.length-1] = a;
</code></pre>

<p>It is not working.I assume that there are some syntax mistakes in this. Please help me on this.</p>
