If you want to insert multiple elements into an array at once check out this Stack Overflow answer: A better way to splice an array into an array in javascript

Also here are some functions to illustrate both examples:

function insertAt(array, index) {
    var arrayToInsert = Array.prototype.splice.apply(arguments, [2]);
    return insertArrayAt(array, index, arrayToInsert);
}

function insertArrayAt(array, index, arrayToInsert) {
    Array.prototype.splice.apply(array, [index, 0].concat(arrayToInsert));
    return array;
}

Finally here is a jsFiddle so you can see it for youselfyourself: http://jsfiddle.net/luisperezphd/Wc8aS/

And this is how you use the functions:

// if you want to insert specific values whether constants or variables:
insertAt(arr, 1, "x", "y", "z");

// OR if you have an array:
var arrToInsert = ["x", "y", "z"];
insertArrayAt(arr, 1, arrToInsert);

made the function more flexible by returning the array. Formated the code at the end.
