Arguments and Return Values

Functions in Lua can take arguments and return values. The syntax is simple and similar to many other scripting languages.

Function with Parameters:

function add(a, b)
  return a + b
end

Calling It:

sum = add(5, 3)
print(sum) -- Output: 8

Multiple Return Values:

Lua supports returning multiple values from a function:

function getCoordinates()
  return 10, 20
end

x, y = getCoordinates()
print(x, y) -- Output: 10  20
