You can do functional programming in assembler if you like. Point #2. Functional programming is not about lambda calculus, monads, morphisms, and combinators. It's about having many small well-defined composable functions without mutations of global state, their arguments, and IO. In other words, if point-free style helps to communicate better in a particular case, use it.

Functions are the most important part of functional programming (especially in JavaScript). Functions are the single source that helps developers to perform functional programming. Generally abbreviated as FP which revolves around functions and it is how we use functions that makes our code functional. Without function, there is no FP. Functional programming and Javascript libraries / frameworks. The world's two most popular client Javascript libraries/frameworks are React and Angular.
