Javascript equivalent to $('body')

Question

Is there a javascript equivalent to the jQuery $('body'), as in the following code? I want to get it running without requiring jQuery.

var content = $('body').html();
var comments = content.match(/<!--.*?-->/g);
if(comments!=null|comments!=undefined){
    for (var x = 0; x < comments.length;x++){
        console.log(comments[x]);
    }
}
else{
    console.log('No Comments');
}

Thanks

Yes, it is document.body

 var contents = document.body.innerHTML;
