In the first part of this book, we will explore the history and importance of design patterns which can really be applied to any programming language. If you’re already sold on or are familiar with this history, feel free to skip to the chapter “What is a Pattern?” to continue reading.
Design patterns can be traced back to the early work of an architect named Christopher Alexander. He would often write publications about his experience in solving design issues and how they related to buildings and towns. One day, it occurred to Alexander that when used time and time again, certain design constructs lead to a desired optimal effect.
