Saying that a particular pattern is the most important might seem like an exaggeration, but I wouldn’t even argue against it. The first time I encountered the concept of a Value Object was in Martin Fowler’s book. At that time, it seemed quite simple and not very interesting. The next time I read about it was in Eric Evans’ “The Big Blue Book.” At that point, the pattern started to make more and more sense, and soon enough, I couldn’t imagine writing my code without incorporating Value Objects extensively.
