Ruby Plus #46: Ruby Idioms Part 6

In this screencast you will learn about inject, splat operator and include? methods and how it is used in Ruby idioms. Paul Morganthall says: Thanks for the screencasts. I just watched Ruby Idioms Part 4 about the splat operator. In the first example, the code looks something like this: fruits = ['apple', 'banana'] a, b = *fruits This works fine, you get the same results without the splat operator: a, b = fruits The splat operator in this case seems to obscure what's going on. I realize that the presence of the splat operator can change the behavior in many other cases ... but not this one.
