Clojure.Programming(2012.3).Chas.Emerick.文字版.pdf

We wrote this book with a couple of audiences in mind. Hopefully, you consider yourself a part of one of them. Clojure matches and often exceeds your current favorite language’s expressivity, concision, and flexibility while allowing you to effortlessly leverage the performance, libraries, community, and operational stability of the JVM. This makes it a natural next step for Java developers (and even JVM developers using interpreted or otherwise not particularly fast non-Java languages), who simply will not accept a performance hit or who do not want to give up their JVM platform investment. Clojure is also a natural step for Ruby and Python developers who refuse to compromise on language expressivity, but wish they had a more reliable, efficient execution platform and a larger selection of quality libraries
