Ruby is a fully object-oriented language. While other OO languages such as Java have a Boolean class, Ruby doesn't have it. It doesn't have methods like to_bool. So, is it bad for Ruby programmers? No, we feel comfortable without Boolean class or to_bool method.
This leads to questions: What is Boolean, what is class and how Ruby designs it? And finally, why doesn't Ruby have Boolean class?
This talk answers "Why doesn't Ruby have Boolean class?" question and explores the world of OOP and language design.
