Chapter 1. Introduction to Design Patterns
In this chapter, we will go through the basics of object-oriented programming and discuss the object-oriented design principles in detail. This will get us prepared for the advanced topics covered later in the book. This chapter will also give a brief introduction to the concept of design patterns so that you will be able to appreciate the context and application of design patterns in software development. Here we also classify the design patterns under three main aspects—creational, structural, and Behavioral patterns. So, essentially, we will cover the following topics in this chapter:
- Understanding object-oriented programming
- Discussing object-oriented design principles
- Understanding the concept of design patterns and their taxonomy and context
- Discussing patterns for dynamic languages
- Classifying patterns—creational pattern, structural pattern, and behavioral pattern
