How to iterate JSON object in Angular 2?
<p>Let's say I have a JSON like this:</p>

<pre><code>{
    "A": [
            {"name": "Aa", "count": "21"},
            {"name": "Ab", "count": "54"}
         ],

    "B": [
            {"name": "Ba", "count": "30"},
            {"name": "Bb", "count": "22"}
         ],

    "C": [
            {"name": "Ca", "count": "40"},
            {"name": "Cb", "count": "33"}
         ],
}
</code></pre>

<p>Output HTML should like this:</p>

<pre><code>[A]
Aa 21
Ab 54

[B]
Ba 30
Bb 22

[C]
Ca 40
Cb 33
</code></pre>

<p>How can I iterate using <strong>angular2 Beta</strong> version?</p>
