How to remove all the odd indexes (eg: a[1],a[3]..) value from the array
<p>I have an array like <code>var aa = ["a","b","c","d","e","f","g","h","i","j","k","l"];</code> I wanted to remove element which is place on even index. so ouput will be line <code>aa = ["a","c","e","g","i","k"];</code></p>

<p>I tried in this way </p>

<pre><code>for (var i = 0; aa.length; i = i++) {
if(i%2 == 0){
    aa.splice(i,0);
}
};
</code></pre>

<p>But it is not working.</p>
