- Before we get started a couple tips for shorthand in Prelude
* > GHCi is an interactive Haskell REPL (Read-Eval-Print-Loop) that comes with GHC. At the GHCi prompt, you can evaluate expressions, load Haskell files with :load (:l) (and reload them with :reload (:r)), ask for the type of an expression with :type (:t), and many other things (try :? for a list of commands).

Words are are a list of chars
In Haskell, lists are a homogenous data structure. It stores several elements of the same type.
One of the most basic data types in Haskell
- List comprehensions?
- Like set comprehensions, normally used for building more specific sets from a larger general set *
- we should mention type signatures too
- NOT AN ARRAY
- ugh, what’s this mean
intListLength (x:xs) = 1 + intListLength xs
