:main
  print("fibbonacci of what number?")
  print(fibb(number_input()))
end

:fibb(x)
  if x <= 1
    return 1
  end
  return x * fibb(x - 1)
end

Easy to use. This example that generates Fibbonacci numbers shows how blz uses intuitive syntax

:main
  for i=1; i < 50; i++
    building_string = ""
    if i % 3 == 0
      building_string = building_string + "bizz"
    end
    if i % 5 == 0
      building_string = building_string + "buzz"
    end
    if building_string == ""
      building_string = i
    end
    print(building_string)
  end
end

Works as expected. Features such as adding strings or printing different types are all handled by the language backend

import Lists
:main
  # Print cubes of even numbers
  evens = range(1000).filter!(x -> x % 2 == 0)
  print(evens.map!(x -> x ** 3)
end

Powerful, concise tools

:main
	# Make a new Ball and name it red_ball
	red_ball = Ball("red", 2)
	
	# Examine its properties
	print(red_ball.name())
	print(red_ball.volume())
	
end

# Constructors can take parameters (that automatically become properties)
constructor Ball(color, radius)
	
	# Objects can also have functions (closures)
	:volume
		return 4/3 * {pi} * (radius ** 3)
	end
	:name
		return "a " + color + " ball with radius " + radius
	end
	
end

Simple object oriented paradigms. Classes are collapsed down to just constructors. Constructor parameters are automatically captured.
