Hands-On Design Patterns and Best Practices with Julia

By: Tom Kwong

Overview of this book

Design patterns are fundamental techniques for developing reusable and maintainable code. They provide a set of proven solutions that allow developers to solve problems in software development quickly. This book will demonstrate how to leverage design patterns with real-world applications. Starting with an overview of design patterns and best practices in application design, you'll learn about some of the most fundamental Julia features such as modules, data types, functions/interfaces, and metaprogramming. You'll then get to grips with the modern Julia design patterns for building large-scale applications with a focus on performance, reusability, robustness, and maintainability. The book also covers anti-patterns and how to avoid common mistakes and pitfalls in development. You'll see how traditional object-oriented patterns can be implemented differently and more effectively in Julia. Finally, you'll explore various use cases and examples, such as how expert Julia developers use design patterns in their open source packages. By the end of this Julia programming book, you'll have learned methods to improve software design, extensibility, and reusability, and be able to use design patterns efficiently to overcome common challenges in software development.

How are positional arguments different from keyword arguments?

Position arguments must be passed in the same order as they are defined in the function signature. They are typically mandatory, but can be made optional when default values are provided. Keyword arguments can be passed in any order that they are written, and they are optional when default value is not provided.

What is the difference between splatting and slurping?

Splatting and slurping have the same syntax but mean different things in different contexts. Splatting refers to the automatic assignment of function arguments from a tuple or array. Slurping refers to the process of passing multiple function arguments, which becomes a single tuple variable accessible from the body of the function.

What is the purpose of do-syntax?

Do-syntax is a convenient way of formatting a block of code that is needed to be...
