I would like to insert a string into an array at a specific index. How can I do that?
I tried to use push()

Well, thats pretty easy. Assuming you have an array with 5 objects inside and you want to insert a string at index 2 you can simply use javascripts array splice method:
var array = ['foo', 'bar', 1, 2, 3],
insertAtIndex = 2,
stringToBeInserted = 'someString';
// insert string 'someString' into the array at index 2
array.splice( insertAtIndex, 0, stringToBeInserted );
Your result will be now:
['foo', 'bar', 'someString', 1, 2, 3]
FYI: The push() method you used just adds new items to the end of an array (and returns the new length)

Note that the returned value from
splice function is an empty array. splice directly applies the changes to the array.
