Rapid Web development many people use Python and other dynamic languages. Clojure is also flexible as a dialect of Lisp. Is it suitable for rapid Web development? Why? What are the advantages and disadvantages of Clojure compared with Python? Rapid Web development many people use Python and other dynamic languages. Clojure is also flexible as a dialect of Lisp. I

Because the whole Storm is to be started and the source code level. so I started learning Clojure. I have heard of functional programming before, and I have heard that Erlang is awesome. I only know it when I contact Clojure. It turns out that Clojure is Erlang in JVM. there are too few materials for Clojure developmen

Recently watching Storm's source code, learn to share the next Clojure grammar.Read the catalogue: Overview Variable Operator Process Control Summarize OverviewClojure is a Lisp dialect running on the JVM, which is a functional programming paradigm, and it can be easily invoked with Java, so that the developed program can combine the advantages of Java and Clojure (Storm), just

In a keynote speech with Martin Fowler, he provided a keen observation report: The legacy of Java is the platform , not the language . The original Java technical engineer had made a great decision to separate the language from the runtime, eventually enabling more than 200 languages to run on the Java platform . This infrastructure is critical to the long-term viability of the platform because the life of the computer programming language is usually very short. Since 2008

that the language can be composed entirely of expressions, ignoring results when not interested in the results. In fact, all functional languages can completely eliminate this distinction, using only expressions. Groovy's if and?: In the Java next-generation language, the separation between traditional imperative language (Groovy) and functional languages (Clojure and Scala) shows evolution to expressions. Groovy still contains statements that are

Java will be a platform rather than a programming language. The original engineers of Java made a wise decision to separate the programming language from the runtime environment, which eventually allowed over 200 languages to run on the Java platform. This architecture is crucial to the long-term vitality of the platform, because the computer programming language generally has a short life cycle. The annual JVM language summit, sponsored by Oracle, started in 2008, provided an opportunity for op

Web Rapid development Many people use Python and other dynamic languages, Clojure as a kind of Lisp dialect, but also very flexible. So is it suitable for fast Web development? What is the reason? What are the advantages and disadvantages relative to python,clojure? Reply content:It should be said to be quite suitable. Clojure Although the history is not long but

longer be needed or can be greatly simplified. Perhaps you are still skeptical about this statement. But a "declining aristocrat" has been reproduced in front of you, it is a functional programming language.Functional programming language once disappeared in the lake, perhaps most people only in the ivory tower to appreciate their demeanor. Its "decline" is not without reason, such as early people on its performance of the question and so on. However, with the wind of the big data age, the heir

Laziness is an important feature of FP. Pure FP should be lazy language, such as Haskell. Of course, the complete lazy problem is that the execution sequence of programs cannot be guaranteed.Clojure compromises between practicality an
