create multidimensional associative array js

Question

I have a problem with my script Javascript. I try to create a multidimensional array with dates in the key.

I would like to have something like

"1" : [ "2018-01-01", "2018-02-02" ]
"11" : [ "2018-01-01", "2018-02-02" ]

But I get something like

1 : [ "2018-01-01", "2018-02-02" ]
2 : ""
3 : ""
..
11 : [ "2018-01-01", "2018-02-02" ]

I'm doing

var array = [];
array[no].push(date);

Thanks for the future help,
MYT.

You should use an Object rather than an Array.

var object = {};
object[no] = object[no] || [];
object[no].push(date);
