In this movie I want to talk about arguments.…When I say arguments, I don't mean the disagreement between two people.…In programming, arguments are going to be a comma-separated list of values that…we pass into our methods.…It's a way that we can get around the problem that we saw in the last movie of…variable scope, because now it doesn't matter what the scope is, when we call…the method, we pass in the values that it's going need.…We don't have to make sure that they have all already been set.…We pass them in at the time that we call them, and that's going to be arguments.…You will also sometimes see arguments abbreviated as just args, so if you see…that, that's what it means.…
It's just short for arguments.…In my ruby_sandbox, you will see that I have a file already called arguments.…It's basically the same code that we have been working with, but I have added…a comment to the top, noting that methods with arguments typically use parentheses.…Methods without arguments typically do not.…But it's completely optional as to whether we use them in both cases.…
