Add items to one array after each item on another array : <p>Basically I need to add each item from one array after each on from another array. So if these are the two arrays:</p>

<pre><code>array1 = [
"item1",
"item2",
"item3",
"item4"
];

array2 = [
"choice1",
"choice2",
"choice3",
"choice4"
];
</code></pre>

<p>I need to make array1 become this:</p>

<pre><code>"item1",
"choice1",
"item2",
"choice2",
"item3",
"choice3",
"item4",
"choice4"
];
</code></pre>

<p>Does anyone have any idea how to do this? Thanks</p>
