At the beginning of this book I will be focusing on a discussion about the importance and history of design patterns in 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.

One of the most important aspects of writing maintainable code is being able to notice the recurring themes in that code and optimize them. This is an area where knowledge of design patterns can prove invaluable.

Design patterns can be traced back to the early work of a civil engineer 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.

In collaboration with Sarah Ishikawra and Murray Silverstein, Alexander produced a pattern language that would help empower anyone wishing to design and build at any scale. This was published back in 1977 in a paper titled 'A Pattern Language'.

Some 30 years ago, software engineers began to incorporate the principles Alexander had written about into the first documentation about design patterns, which was to be a guide for novice developers looking to improve their coding skills. It's important to note that the concepts behind design patterns have actually been around in the programming industry more than likely since its inception, albeit in a less formalized form.
