Functional Programming

• Balancing speed and readability is key
• if you can get your code to read semantically using good varible names this greatly improves the quality of your code in regards to readability.
• referential transparency: same input = same output
• Functions can be passed and used as data
• Higher-order function are those that use multiple functions to resolve results
• Side-Effects: are unintended outputs and inconsistent data
• functions taking in variable data are not “pure functions”

Refactoring

• detemanistic: same input same output
• immutable: cant change after its made
• suff with random is not immutable
