The CPU is a Honey Badger

Honey Badger Don't Care

• To a computer, it's all ones and zeros
• Abstractions make your code make sense to humans

Data Tiers

• Structs

  • put several pieces of related data together

• Data Structures

  • List, Stack, Queue, Hash, Tree, Heap

Code Tiers

• Closures
  • function plus scope of defining function
  • allow several chunks of code to share state

Combining Code & Data

• Objects

  • encapsulate data and behavior
  • allow several chunks of code to share extra state

• Classes

  • reuse code and data for different instances

Other Abstractions

• Immutability

  • values (like variables that you can't modify)
  • adding this constraint can make your code simpler and more scalable

• More...?
