Master pure functions and immutability principles
Implement higher-order functions and closures
Apply recursion for elegant problem solving
Transform functions with currying and decorators
Understand sum types and functional data structures
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.
Learn about the difference between OOP and functional styles, and what the real difference is: imperative vs declarative
First class and higher order functions are foundational to everything we do in the functional paradigm
My favorite part of functional programming is the focus on pure functions that are easy to test and reason about
While not unique to functional programming, recursion is a powerful tool that is used often when trying to avoid imperative code
Learn how to transform functions into other functions to write more abstract and generalized code
Learn about encapsulating state within functions and how to use closures to write more expressive code
Learn to transform a function with multiple parameters into a series of functions with one parameter
Learn about Python's decorators and how they're essentially syntactic sugar for higher order functions
Learn about sum types, a powerful way to represent data that is used in many functional languages
