Sorry I meant I don't see the appeal in contrast to using CSS in JS solutions, BEM clearly offers better separation of concerns compared to traditional CSS, but this problem is already solved when using CSS in JS, because you explicitly import the styles you want to apply to an element, having to line up class names in your CSS and DOM is a non-issue as the classnames are autogenerated
