<div>
As explained by <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach#Syntax" rel="ugc">the documentation of foreach</a>, the first parameter to the callback--the parameter a in your example--is the current item in the iteration. The second parameter is the current index of that item, and the third parameter is the array itself. 
 
So simply: 
 

<pre><code class="code-1 nolinks" id="code-20-42689533-1">var currentElem = a;
</code></pre>
</div>

<div>
be sure to use friends.forEach and not persons.forEach 
(sorry if that's sound stupid) 
 

<pre><code class="code-10 nolinks" id="code-20-42689686-1">var friends = [
 {name:'John', age:51},
 {name:'Bill', age:20},
 {name:'Mary', age:29}
];

friends.forEach(function(a, b, c) {
 var currentElem = a;
 var currentName = currentElem.name;
 var currentAge = currentElem.age;
 alert(&quot; - name :&quot;+currentName + &quot;\n - age:&quot;+currentAge);
});
</code></pre>
</div>

<div>
<pre><code class="code-10 nolinks" id="code-20-42690195-1">	var friends = [
	 {name:'John', age:51},
	 {name:'Bill', age:20},
	 {name:'Mary', age:29}
	];

	friends.forEach(function(a, b, c) {
	 var currentElem = a;
	 alert(currentElem.name+'::'+currentElem.age);
	});
</code></pre>

What would you write instead of XXX &nbsp;to get the current element of the array, while iterating on the elements of the array?

Identify JavaScript Element

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
