Node.js/Javascript Multidimensional Array with dynamic Key

Question

I request some data from my database which returns me an Value which is the Type of an int.

var id = databaseReturn["id"]; //-> int 2

Now when I try to make an Array with and key of that value it doesnt work because it is an int, but even after converting it to a String it doesnt work.

id = String(id); //Should be -> String "2"
array[id] = []; //array[2] = [] but should be array["2"] = []

How do I fix that ?

Don't use arrays if you're not going to use int indexers. Just use Object for it:

var obj = {};
obj[id] = //whatever

When you use objects, it will convert the key automatically to string too.
