I have to admit I’m far from a FP guru, very little experience with true functional languages like Haskell etc. For me it’s more a question of style and applying functional paradigms when possible, eg treating functions as first class citizens, making heavy use of .bind() and passing functions as arguments. I use ES6 via Babel and actually find it to be quite expressive and powerful when used correctly. I just try to keep my functions very small with tight separation of concerns. There are lots of libraries to make JS “more functional,” as the sibling comment alludes to, but I find vanilla JS (or at least ES6) already has many of the features necessary for functional programming, as long as you make the conscious choice to use it that way.
