# Functions

Functions are declared using the function keyword. The function keyword is followed by the function name. Parameters come after the function name, and are seperated with a comma. A function with parameters is declared in the following order:

function add(a, b)

Here add is the name of the function, which takes in a and b.

# Return

Functions can return data using the return keyword.

function add(a, b)
  return a + b

This function takes in a and b and returns the value of a + b.

Return statements don't require a return value, but can also be used to break out of a function.

function divide(a, b)
  if b is 0
    return
  return a / b

In this example the function returns nothing if b is 0, else it returns a / b.

# Executing

You can execute a function as following

function add(a, b)
  return a + b

add(2, 3)

This would call add with 2 and 3, which returns 5.
