This is a very short book, so this review will be short as well! Reading Ruby Pocket Reference is alot like reading a dictionary. It’s difficult to get drawn into the narrative because there is no narrative. And yet therein lies the advantage of this book. By going through Ruby syntax one element at a time, you’re likely to learn things you never knew you never knew.
For example, some Rails features that I thought were exclusive to Rails are actually part of Ruby.
Array.first actually makes reference to the
first method that is part of Ruby’s array class. It’s not magic. It’s rational computer science. Some readers will dismiss this as obvious, but not me. Call me a perpetual student!
Reading Ruby Pocket Reference gave me an appreciation for the language beneath Rails. I am growing into a better developer as a result. The small form factor makes it very easy for me to carry this one around. If you’re a Ruby developer, you might consider carrying one as well.
