Multiple tier / dimension array in javascript

It is possible to define a multiple tier javascript array  that each “member”can contain more primitive data types or array object,  below example shows 3 tier array.

• Top tier holds array object, eg:  new Array(“002″,new Array(“BB1″,“BB2″))
•  Second tier array holds two dimension data: a string type “002″, and another array object new Array(“BB1″,”BB2″)
• Third tier holds multiple dimension data: “BB1″,”BB2″

<scripttype=”text/javascript”>

var array_demo = new Array( new Array(“001″,new Array(“AA1″))  ,   new Array(“002″,new Array(“BB1″,“BB2″))   ,   new Array(“003″,new Array(“CC1″,“CC2″,“CC3″))    );

</script>
