CSS in JS - Pros and Cons

It's really nice for that as well as one other point I should I should mention about this is maintainability. If you look at some CSS, you should be able to say I can totally delete that with confidence and know that it will not break my app. So being able to pass in props and actually modify or have real JavaScript logic in yourCSS is a nice killer feature. You can develop some really nice complex components that accept properties to modify them and things like that.
