Create HTML table from javascript array

I want to get all classes of the HTML element on my page, split it and store it in array. After that I want to write it into my table in the div with the id "table" which I already have.

So far I have this code:

var string = $('html').attr('class');
var array = string.split(' ');
var arrayLength = parseInt(array.length);

for (i=0; i<=arrayLength; i++) {
    // code
}

<div id="test><!-- table goes here --></div>

Can you help me with the rest?

btw, the HTML element has the classes from a modernizr.js.

PS: The code is combination of pure JS and jQuery. Because I dont know how to get all classes of the HTML element in pure JS. Any Idea?
