Difference Between Argument And Parameter In Ruby On Rails ? |

Answer» A parameter represents a VALUE that the METHOD expects you to pass when you call it. An argument represents the value you pass to a method parameter when you call the method. The calling code supplies the arguments when it calls the method. In simple WORDS, PARAMETERS APPEAR in method definitions; arguments appear in method calls. For example, in below method, variables param1 and param2 are the parameters def foo_method(param1, param2): ....... endwhile calling the method, arg1 and arg2 are the arguments foo_method(arg1, arg2)A parameter represents a value that the method expects you to pass when you call it.
