What you'll learn in this Python 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.

Chapter List

1
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

This course was HARD, but I think it will be useful. Things came together somewhat by the end.

I feel like this course was quite agonizing to get through at some points, I'm not sure if that is a fault of me just struggling to understand or the teaching being less effective here.
