method_default_value.rb

# Method default value
# In Ruby, you can define default values for method parameters. 
# This allows you to call a method without providing all the arguments, and the default values will be used for any missing arguments.

def greet(name = "Guest")
  puts "Hello, #{name}!"
end

greet("Luthfi") # Output: Hello, Luthfi!
greet # Output: Hello, Guest!

# But better practice use keyword arguments with default values, because it can make your code more readable and allows you to specify which arguments you are providing when calling the method.
# See the method_keyword_arguments.rb file for more details about keyword arguments with default values.
