Why htmlb is prefered to normal html code ?

Hi,

I'am new to this forum, so excuse me for such basic questions.

We have already developed 2 small projects (vendor portal/gate computer system ) in my co using BSP , but since we had a background of asp/jsp/javascript we easily developed all the layouts in plain html lang , and we used max javascripting where we required , which we found more easy and confortable.

So may I know some major advantages of using htmlb besides the normal reasons of look and feel , as by and large almost every thing what htmlb does same can be done by javascript/html.
