How can I add an array to an array of arrays using jQuery?

I have an array, as below:

var cString =   [

            ['1','Techdirt','www.techdirt.com'],

            ['2','Slashdot','slashdot.org'],

            ['3','Wired','wired.com']

            ];

to this array I want to add another in the same format:

var test = ['4','Stackoverflow','stackoverflow.com']

I've tried using:

var newArray = $.merge(cString, test);

But console.log(newArray); outputs:

[►Array,►Array,►Array,'4','Stackoverflow','stackoverflow.com']

So I'm assuming that I'm missing something obvious. Or attempting something stupid...help?

jQuery is not needed for this. Just use the Array's .push() method to add it to the main array.

var test = ['4','Stackoverflow','stackoverflow.com']



cString.push( test );

What $.merge() does is it walks through the second array you pass it and copies its items one by one into the first.

EDIT:

If you didn't want to modify the original array, you could make a copy of it first, and .push() the new Array into the copy.

var cString =   [

            ['1','Techdirt','www.techdirt.com'],

            ['2','Slashdot','slashdot.org'],

            ['3','Wired','wired.com']

            ];



var test = ['4','Stackoverflow','stackoverflow.com']



var newArray = cString.slice();



newArray.push( test );
