OCaml Programming Language
Functional language
immutable data structures
based on mathematical functions
Value Oriented Programming
Expressions run to calculate a value (int, string, boolean)
If-then-else
useful way to choose between two different result values based on a boolean condition
let declarations
two declarations can have the same identifier...the most recent identifier will be used
let x = 5
let x = 11
Local identifier: let x = 3 in x + 4
let x = 3
let f = (x : int)
let f = (x : int ) (y : int)
Strongly Typed Language: cannot intermix values with differing data types
Commands
importing other ocaml modules or libraries
running program test cases
Printing to the screen
Commands don't calculate any useful value
;; print_string "hello world"
;; run_test "name of test" (function name)
;;print_endline "Hello, World"
