I do not understand what you mean by "fireball" effect

JavaScript isn't capable of any acceptable performance for anything like that - at least not in browsers. The flash ActionScript is more capable, as is the Adobe EScript for SVG. However, that is because the hosts in those cases provide JavaScript with graphics capabilities.

how about fog effect?
is it too hard by javascript?

JavaScript as employed in browser have nothing to work with for graphics, really. You need to work with the DOM and CSS. In other words, it's great for drawing a limited number of rectangles, but not much more than that.
