商品描述
Learn the principles behind object-oriented programming in Ruby and within a few chapters create a fully functional Ruby 3-based application. You'll gain a basic understanding of many ancillary technologies such as databases, XML, web frameworks, and networking - some of which will be needed for your first Ruby application. Based on the bestselling first and second editions, Beginning Ruby 3, 4th Edition is a leading guide to learn Ruby from the ground up.
The new edition of this book provides the same excellent introduction to Ruby as the previous editions plus updates for the newest version of Ruby, including performance through an improved allocator, decreased heap fragmentation and more. Also, added: details on the just-in-time compiler, fewer limits on GIL (Global Interpreter Lock), and a static type checker.
You'll see why the light and agile Ruby programming language remains a popular open source scripting option for developers building today's web applications. This book can also be used as a textbook or companion to a textbook on beginning Ruby programming. After reading and using this book, you'll have a firm handle to program in the Ruby language.
What You Will Learn
- Discover the fundamentals of Ruby and its object-oriented building blocks
- Use the Ruby libraries, gems, and documentation
- Work with files and databases
- Write and deploy Ruby applications
- Harness the various Ruby web frameworks and use them effectively
- Do network programming with Ruby
