General things

• Functional (at least mostly)
• Everything is an expression (i.e. evaluates to something)
• Every function is curried
• Tab sensitive
• Modules are defined by file names

Variable declaration

# Primitive
let boolean = True
let integerNum = 1
let floatNum = 1.3
let char = 'c'

# Other
let array = [1,2,3]      # homogenous
let string = "string"    # is array of chars
let tuple = (1, "hello") # heterogenous, immutable

Conditions

let x = 1
let y = 2

let res =
  if (x - y) > 0:
    let sum = x + y
    sum
  elif (x + y) < 2:
    x 
  else:
    y

Functions

let add = (x, y) -> x + y
let multiply = (x, y) -> x * y

let doSomeMoreStuff = (x, y) ->
  let sum = add(x, y)
  let mulBy2 = multiply(2) # partial application
  let prod = mulBy2(sum)

  prod # last thing is returned

# does the same as function above
let doStuffWithComposition = (x, y) ->
  add(x, y) |> multiply(2)

let apply = (func, value) -> func(value)

# functions are fist class citizens
apply(print, "Hello there")
