The target audience is modern application developers working in a collaborative environment. Intentionally, this represents a great number of backgrounds and industries as the patterns can be applied to a wide range of solutions. As this book dives into the code to explain the patterns covered, readers should have a background in software development—this book should not be viewed as a how to program book but more of a how to program better book. Because of this, the target audience will range from junior developers to senior developers, to software architects and designers. For some readers, the content will be new; for others, it will be a refresher.
