Functional programming

In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program.

Explore the increasingly popular paradigm of functional programming in JavaScript! You’ll learn how to wield and manipulate functions to develop more readable, maintainable and manageable codebases. You’ll go under the hood of powerful techniques like: Higher Order Functions, Function Composition, Pure Functions, and Immutability of State.
