JavaScript: Adding to an associative array

Question

I have a function called insert which takes two parameters (name and telnumber).

When I call this function I want to add to an associative array.

So for example, when I do the following:

insert("John", "999");
insert("Adam", "5433");

I want to it so be stored like this:

[0]
{
name: John, number: 999
}
[1]
{
name: Adam, number: 5433
}

Answer 1

Something like this should do the trick:

var arr = [];
function insert(name, number) {
    arr.push({
        name: name,
        number: number
    });        
}

Answer 2

I would use something like this;

var contacts = [];
var addContact = function(name, phone) {
    contacts.push({ name: name, phone: phone });
};

// Usage
addContact('John', '999');
addContact('Adam', '5433');

I don’t think you should try to parse the phone number as an integer as it could contain white-spaces, plus signs (+) and maybe even start with a zero (0).
