Even so, the example is a tad puffed up: if (count > 100) { $el.removeClass('low-value'); $el.addClass('high-value'); } else if (count < 50

Even so, the example is a tad puffed up: if (count > 100) { $el.removeClass('low-value'); $el.addClass('high-value'); } else if (count < 50) { $el.removeClass('high-value'); $el.addClass('low-value'); } else { $el.removeClass('high-value'); $el.removeClass('low-value'); } Compare to how this would normally be written: $el.toggleClass('high-value', count > 100); $el.toggleClass('low-value', count < 50);
