Method Parameters

Method parameters, also called arguments, are the values you pass into a method when you call it. There are several types: required parameters, which must be provided; optional parameters, which have default values if not provided; and variable-length arguments (using *args), which allow you to pass in an arbitrary number of arguments as an array. Arbitrary keyword arguments (using **args) allow you to pass arguments by name, and can also be required or optional. Block parameters (using &block) allow you to pass a block of code to a method.
