My gateway into functional programming was via the concepts of it, things like immutability, declarative language and map/filter/reduce functions which are present in UI frameworks like ReactJS. If you’re creating a user interface of some kind it’s a lot easier to get feedback and to actually see something working while directly applying FP concepts. I would also recommend Typescript over JavaScript, not only for the better experience but also as there is a lot of overlap between type theory and FP.
