Conceptually, the book is a mediocre method of learning a language or tech subject. Anything "Learn X the hard way" with recent commits will be more helpful. The concept is to run the exercises needed to gain fluency in the key features and accessing/understanding the core documentation. A standalone book frozen in time with idiosyncratic documentation is not helpful. At their best, books can provide analogies and parables to build a narrative about a technology without specifics.
