I love FP, but I wouldn’t let someone introduce these abstractions into our JavaScript code base, as they ramp up the complexity in understanding code that can

  A loop isn't simpler than recursion or high-order functions since it introduces state and is noisy, but most examples of JavaScript/TypeScript + FP involve heavy usage of utility libraries that aren't community standards (like a Prelude). Not to say these libraries aren't valuable or of good quality, but it's a lot to learn atop the language itself for a new hire and can lead to some library lock-in as said functions will end up all over the code. The folks that preach the libraries the most are the ones that usually want their JS/TS to look like Haskell which ends up making it impossible for outsiders to follow (so now I need to know JavaScript + TypeScript + Haskell + the weird esoteric version these people write?). And those folks should be allowed and encourage to just write some ML-flavor-to-JavaScript code instead which can often be easier to for a new hire to follow since all examples will follow community standards (wouldn't be surprised if the coders were happier writing it too).
