Question

I need to push a new array as the value of a parent array key.

this is my array.

asd[
[hey],
[hi]

]

i would like to return.

asd[
[hey]=>[],
[hi]
]

i do:

var asd = new Array();
asd.push(hey);
asd.push(hi);
asd[hey].push(new Array());

so obviously is not ok my code 

Answer 1

Instead of new Array(); you should just write []. You can create a nested array like this

myarray =
[
    "hey",
    "hi",
    [
        "foo"
    ]
]

Remember that when you push things into an array, it’s given a numerical index. Instead of asd[hey] write asd[0] since hey would have been inserted as the first item in the array.
