Multidimensional array in JavaScript

Hi,

I am not sure if what I am trying to do is possible with JS but I hope it is. I have an array like the following in PHP and I am trying to construct it in JavaScript.

<?php
$myArray = array(
	'part1' => array('id' => 75, 'name' => 'blue_part'),
	'part2' => array('id' => 14, 'name' => 'green_part'),
	'part3' => array('id' => 40, 'name' => 'red_part'),
);
?>

I know how to create a basic array in JS like the following:

var myArray = new Array('part1', 'part2', 'part3');

How can I add the multidimensionality to the JS array?

Thanks for all ideas.

The JavaScript equivalent is:

$myArray = {
    'part1' : {'id' : 75, 'name' : 'blue_part'}, 
    'part2' : {'id' : 14, 'name' : 'green_part'}, 
    'part3' : {'id' : 40, 'name' : 'red_part'}, 
};

Thank you.
