How to change normal array form to associative in javascript

I have this code:

$(document).ready(function() {
	var meal_qty = new Array(); 
	var label_options = new Array(); 
	var qty_options = new Array();

	$(".protein-option").click(function() {
	
		var meal_label_qty = $(this).attr("label_option");
		var id_mon_qty = $("#qty1").val();
		var id_tues_qty = $("#qty2").val();
		var id_wed_qty = $("#qty3").val();
		var id_thur_qty = $("#qty4").val();
		var id_fri_qty = $("#qty5").val();

		meal_qty.push(meal_label_qty,id_mon_qty,id_tues_qty,id_wed_qty,id_thur_qty,id_fri_qty);

		alert(meal_qty);
});
});

Select allOpen in new window

This is my output:
And it keeps adding, I want my outcome to be:

var meal_qty
{
[1012] {
               [mon] => 'qty1value',
              [tues] => 'qty2value',
              [wed] => 'qty3value', ...}
(ALL THE WAY TILL FRIDAY)
[10112] {
               [mon] => 'qty1value',
              [tues] => 'qty2value',
              [wed] => 'qty3value',
}

}

Select allOpen in new window

How can I do this, meaning put the meal_label_qty as the associative of an array
