convert json array to javascript array

Question

i have a json array that i want to convert into a plain javascript array:

This is my json array:

var users = {"0":"John","1":"Simon","2":"Randy"}

How to convert it into a plain javascript array like this:

var users = ["John", "Simon", "Randy"]

Answer 1

users is already a JS object (not JSON). But here you go:

var users_array = [];
for(var i in users) {
    if(users.hasOwnProperty(i) && !isNaN(+i)) {
        users_array[+i] = users[i];
    }
}

Edit: Insert elements at correct position in array. Thanks @RoToRa.

Maybe it is easier to not create this kind of object in the first place. How is it created?
