Is there a way to incorporate an array into an array of arrays with jQuery?

Question

Is there a way to incorporate an array into an array of arrays with jQuery?

I am working with an array shown below:

var cString =   [
            ['1','Techdirt','www.techdirt.com'],
            ['2','Slashdot','slashdot.org'],
            ['3','Wired','wired.com']
            ];

In order to expand this array, I want to add another entry in the same format:

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

I attempted to combine them using:

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

However, when I did a console.log(newArray);, it displayed:

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

This makes me think that I might be overlooking something basic. Can someone please help me figure out what's wrong?

You don't need jQuery for this task. Simply utilize the Array's .push() method to append it to the main array.

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

mainArray.push( collection );

The purpose of $.merge() is to iterate through the second array provided and copy its elements individually into the first array.

UPDATE:

If you prefer not to alter the original array, you can create a duplicate first and then use .push() to include the new Array in the duplicate.

var mainArray =   [
            ['1','Techdirt','www.techdirt.com'],
            ['2','Slashdot','slashdot.org'],
            ['3','Wired','wired.com']
            ];

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

var duplicateArray = mainArray.slice();

duplicateArray.push( collection );

If you're looking to create a fresh list instead of modifying the existing one, you can use the Array#concat method to combine arrays together. This is an alternative approach to the push method discussed by Patrick:

var newList = originalList.concat([['8','GitHub','github.com']]);
