help coding a hash table

How do I create a javascript associative array or a JSON object of
hours, minutes, and seconds because with code?
I think my JSON object is right but how do I create the object with 60
minutes for each hour and then 60 seconds for each minute?
Or how do I fill the array so that it is assocative?
data["hours"] =
"12:00","13:00","14:00","15:00","16:00","17:00","18:00","19:00",
"20:00","21:00","22:00","23:00","24:00",
"1:00","2:00","3:00"..."11:00"]
data["minutes"] =
"00","01","02","03","04","05","06","07","08","09","10".... "60"]
data["seconds"] =
"00","01","02","03","04","05","06","07","08","10","11"...."60"]

var oTime = [12:00, 13:00, 14:00, 15:00, 16:00, 17:00, 18:00, 19:00,
20:00, 21:00, 22:00, 23:00, 24:00 ]
};
{ data:[{ 'hours': '12:00', 'minutes':
'00','02','03','04','05','06','07','08','09','seconds:
'00','01','02','03','04','05','06','07','08' }, ]
}

Many thanks,

Don't.
If you must write a program that puts all integers between 0 and
1.000.000.000 on the screen, you don't write a program like this:
document.write(1);
document.write(2);
document.write(3);
.......
document.write(1000000000);

Or do you?

That is why the job is called programming. You write a loop.
I cannot think of any valid reason to construct an object that holds
every hour, minute and second you can think of.
You simply store the hour, minute and second in a variable (or in 3
variables if you prefer).
There is no need to preconstruct something that holds every possible
value for a second (0 to 59).

So my advice: Rethink your problem.

About associative: If you create an empty object, just can add
"properties" with values to it to your heart's liking. That way you have
your associative array behaviour.

var myTime = new Object();
myTime.firstName = "J.";
myTime.famName = "Rough";

However, by default there are no empty objects (although there are
proprietary ways like assigning to the `__proto__' property to create them,
leaving a from then on crippled object). Even Object instances inherit from
Object.prototype by default.

As a result, some property names (like "toString") are already used. So you
should avoid assigning to the corresponding properties in order to store
user data. Which points out *again* _that there are no *built-in*
associative arrays in ECMAScript implementations_ (but you can try to
emulate them, like with jsx.map.Map [1]).
