4.10. Summary

Hefty tomes have been written on the subject of Ruby programming (see Appendix A), and this and the previous chapters alone cannot possibly do Ruby full justice, particularly when it comes to advanced topics (such as metaprogramming).

Ruby's coverage within this book is meant to be a solid language foundation upon which you can approach the world of Rails. Whenever the need for further Ruby-specific knowledge arises throughout the book, I have ensured that I've covered it by augmenting topics that have already been covered in the current and prior chapter.

In the next chapter you finally get to play with Rails, and I'll guide you step-by-step as you create a basic sample application to illustrate how Rails is used and how it works in practice.
