Working with Ruby there are times you want a method to have required arguments without chaining multiple if else statements
A simpler and easy way to handle required arguments is,
# define a method with named arguments like this results in an # error when name is not provided def greetGuest(name:) puts "Welcome #{name}!" end # invoking method without name will throw ArgumentError greetGuest # ArgumentError: missing keyword: name greetGuest(name: "Salley" ) # Welcome Salley! And even better you can have default arguments like:
def greetGuest(name: "Anonymous Guest") puts "Welcome #{name}!" end # invoking method without name will use the default argument greetGuest # Welcome Anonymous Guest!
