Hash, Array, are classes in ruby. A class is a combination of what an object can do (behaviors) and what an object is (attributes).

WET code: write everything twice (not a good practice)
DRY code: do not repeat yourself (gold standard)

Refactoring: cleaning up code (you might not always write the most efficient code first)

Command + Control + up/down arrow: Move selected line of code up or down

Control + c: Stop infinite loop that is running

if statements are the opposite of unless statements
until statements are the opposite of while statements
