convert array to string in javascript
<p>I want the text to be printed without commas.</p>

<pre><code>&lt;html&gt;
&lt;head&gt;
&lt;title&gt;Reverse&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;form name="rev"&gt;
Enter the string : &lt;input type="text" name="str"/&gt;
&lt;input type="button" value="click" onclick="rev1()" /&gt;&lt;br&gt;
reverse of given string : &lt;input type="text" name="res"/&gt;
&lt;/form&gt;
&lt;script type="text/JavaScript"&gt;
function rev1(){
var a=rev.str.value;
var b=[];
var i,j=0;
    for(i=a.length-1;i&gt;=0;i--){
    b[j]=a[i];
    j++
}
//rev.res.value=b;
alert(b);
}
&lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>If I give the input as <code>abc</code> I am getting an output as <code>c,b,a</code>, but I want it as <code>cba</code>.</p>
