I think this would be equivalent :
```
boolean isActive = $(sidebar).hasClass(appResources.style().active());

$(sidebar).toggleClass(appResources.style().active());
$(menuToggle).toggleClass(appResources.style().active(), !isActive);
```
Although I'm not sure why you can't only toggle both classes? Is there a place where you only toggle the .active() class only one one element? From this code it seems that the .active class is not always applied to menuToggle when it's applied to sidebar
