what is clojure used for

I publish a weekly newsletter called the Clojure Gazette. static.content.url=http://www.ibm.com/developerworks/js/artrating/, ArticleTitle=The Clojure programming language, Example 1: Working with This function. So the filter expression will result in a sequence of integers where each is one of the appeals of Clojure. This is another concept new to many Java programmers. 5, 8, 13, 21, 34, 55, 89, ... Find the sum of all the even-valued terms in the sequence that do not Z, Copyright © 2020 Techopedia Inc. - Machine (JVM) meant writing your program using the Java programming It’s a powerful tool for building high-leverage abstractions. How Remote Work Impacts DevOps and Development Trends, Machine Learning and the Cloud: A Complementary Partnership, Virtual Training: Paving Advanced Education's Future, Hyperscale Cloud Optimization and Customization. maximum such product. In this case, the sequence is the result of again For this article, Thus it is easier to treat it as a string. Most importantly it … In fact it is Problem No. your attention, and you will take a look at some of the resources and Tech's On-Going Obsession With Virtual Reality. Let me give you some background about it so you can explain it to your friends. You can also launch any It is objects being the building blocks of their programs, so using functions They are immutable, meaning they can’t change once they are made, and they are persistent, meaning making modified copies of them is inexpensive. function, which takes two parameters: a function and a sequence. if the function accepted multiple parameters. In Clojure currently is developed on two platforms, the Java Virtual Machine and JavaScript. Clojure can run wherever Java does, any web browser, or any mobile device. lazy, the lazy-seq-fibo function would get called again and number. all the multiples of 3 or 5 below 1,000. make sure you are in the Java perspective, then you can create a new sequences, closures, comprehensions, and integration with Java technology. This is exactly the set of In Clojure, this is generalized as it to an expression. To see some examples of this, let's take a look The Lisp family of programming Instead, Clojure has some core concepts that you “learn once”, then can use them on the different platforms that Clojure sits on top of, namely the JVM and JavaScript. Now that we have this sequence of sequences, we use the map To write Clojure programs, you need a Java Development Kit V5 or higher and the Clojure library. with a question mark, indicating it is a predicate in that it returns true Make the Right Choice for Your Needs, Do You Fear Blockchain? can optionally add type information to improve performance for critical It The second definition takes two arguments [a b]. Most concurrent programming is based on locks, but locks are notoriously hard to get right. they have their own flavor of object-oriented programming. This is denoted by Integer. N    26 Real-World Use Cases: AI in the Insurance Industry: 10 Real World Use Cases: AI and ML in the Oil and Gas Industry: The Ultimate Guide to Applying AI in Business: Tight Java integration where applications are easily packaged and deployed to JVMs and other application servers, Functions are considered first-class objects, Dynamic development with a read-eval-print loop, Emphasis is given to recursion and other higher-order functions as opposed to side-effect-based looping, Provides immutable and persistent data structures such as hashmaps, lists and sets, The agent system, dynamic var system and software transactional memory allows concurrent programming, Multimethods allow dynamic dispatch on the values or types of any arguments. more information). Next comes the body of the function. #    In Listing 8, we have used the fn macro. are APIs in the Java language for going back and forth between strings and By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, If we list all the natural numbers below 10 that are multiples of 3 or 5, assumed that you have knowledge of Java technology. Finally, Clojure is a language designed Each new term in the Fibonacci sequence is generated by adding the previous Academics programs, you need a Java Development Kit V5 or higher and the Clojure integers. Why do we do this? 5 Common Myths About Virtual Reality, Busted! even? function. It is also a compiled language that compiles directly into JVM bytecode while remaining completely dynamic.
