Learn Functional Programming

An interactive online course

Functional programming is back in vogue. There's a reason front-end frameworks like React and Vue are moving toward functional programming, and after this course you'll more than understand its benefits. We'll dive in-depth into all of the foundational concepts of functional programming in a familiar language, Python!

Chapter list

1
What is Functional Programming?
Learn about the difference between OOP and functional styles, and what the real difference is: imperative vs declarative
2
First Class Functions
First class and higher order functions are foundational to everything we do in the functional paradigm
3
Pure Functions
My favorite part of functional programming is the focus on pure functions that are easy to test and reason about
4
Recursion
While not unique to functional programming, recursion is a powerful tool that is used often when trying to avoid imperative code
5
Function Transformations
Learn how to transform functions into other functions to write more abstract and generalized code
6
Closures
Learn about encapsulating state within functions and how to use closures to write more expressive code
7
Currying
Learn to transform a function with multiple parameters into a series of functions with one parameter, and why you might want to do that
8
Decorators
Learn about Python's decorators and how they're essentially syntactic sugar for higher order functions
9
Sum Types
Learn about sum types, a powerful way to represent data that is used in many functional languages
