functional javascript can increase code clarity if written well. Certainly ramda is usually a huge improvement when making mutations in a reducer. compose()'ing a bunch of HOCs is essentially the same as having mixins (and it's exactly the same as @decorators), just with a slightly different syntax. I think it's mostly down to the paradigm you're most familiar with. Classes are normal to OO developers, functional composition is normal to FP developers.
