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?

you can use merge function like this

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

In addition to push as described by patrick, if you want to create a new list rather than changing the old, you can add arrays together with Array#concat:

var newArray= cString.concat([['4','Stackoverflow','stackoverflow.com']]);

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 );
