The Book Of Ruby - new chapter: Arrays, Hashes etc.

Free eBook and source code
by Huw Collingbourne
Thursday 17 July 2008.

The Book Of Ruby now contains just under 80 pages and comes complete with 57 little ready-to-run Ruby programs to illustrate every topic described in the text.

The latest chapter takes a look at the fundamental Ruby collection types - arrays and hashes (and a few others). It goes beyond the basics to look at array methods, treating hashes as arrays, defining your own comparison operator methods, indexing over nested arrays and much more. As always both the eBook itself and the sample programs are provided free.
