Assuming this is in a scroll event, so it gets fired a whole bunch:
element.setStyle('top', 100);
or:
if(element.getStyle('top') != '100px') element.setStyle('top', 100);
?
The first doesn't care, it just sets the style 100 times in a row.
The second checks if it even needs to set it.
So is the logic to find out more intense than just doing it anyway? I
imagine it is but I'm often surprised.
