"Clojure is elegant and pragmatic; It helps me focus more on solving business problems. "
Unlike static languages such as Java, Clojure is a dynamic language, and dynamic typing means that these types are deduced dynamically by Clojure when the code is run, without any restrictions on compilation.

It's hard to write simple solutions to complex problems. but every experienced programmer has also stumbled on areas where we 've made things more complex than necessary, what you might call incidental complexity as opposed to complexity that's essential to the task at hand (Moseley 2006 ).

It was too late to find clojure. Unfortunately, I am a very good Java programmer and I am also good at Emacs and familiar with lisp. Don't know clojure? How many years have you missed.
It's not too late. Start now.

platform provides a more flexible method scheduling mechanism than the Java language. In this issue of "functional thinking", Neal Ford will explore the scheduling mechanisms in functional languages like Scala and Clojure to show new ways of thinking about executing code.

new languages derive from the great difference between imperative and functional, which is one of the most valuable areas to explore in this series of articles.
Recently two large-scale JVM programming languages were voted (Poll 1, poll 2). These polls produce some very interesting data. Because voters come from different camps, the results of the two polls are slightly different.Clojure has progressed very well in my voting (leading Scala and groovy), because many of the voters are from

What is metaprogramming?
Metaprogramming is the use of code to modify or create other code.It is primarily a developer tool and acts as a force multiplier, allowing large amounts of predictable code to be generated from just a few statements in the host language (or "metalanguage "). it
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
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

"No inheritance extensions, part 1th" mainly discusses the mechanism for adding new methods to existing classes in Goovy, Scala, and Clojure, which is one of the ways in which the Java next-generation language implements no inheritance extensions. This article explores how Clojure protocols can expand Java extensions in an innovative way and provide an excellent solution for expression problems.

What is ClojureClojure is a dynamic, strongly-typed language that resides on the JVM.Features of the Clojure:
Functional programming basics, including a set of persistent data structures that can be comparable to typical mutable data structures

After seeing "hackers and painters", are you so curious about lisp? Then, how many pages of ACL (ANSI Common LISP) Is it daunting? Sigh: it would be nice if you could write lisp code on. net clr one day! This day has arrived. This is clojure CLR. Looking at the language conversion matrix, clojure has a strong parasitic capability, which is even more powerful than Javascript. It has a place on CLR.As a begin
In a previous e-mail, I pointed out that among the many changes, the most obvious is that the development of using other popular languages on the JVM on the Java domain has become more and more rapid. Some old and new-created JVM-based languages---JRuby and Jython, Java-style languages---Groovy and Scala and brand, new languages---Clojure and Kotlin, These languages give us a choice------get the performance and reliability of the JVM but can use a dif

Lisp is a programming language known for its expressiveness and power of functionality, but it is generally considered unsuitable for general use. Clojure is a Java™The appearance of the Lisp dialect on the platform has completely changed this situation. Nowadays, you can use the powerful functions of Lisp wherever you have a Java virtual machine.

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.
