Should I hold back some ideas for after my PhD? people claiming Clojure as a skill – surprisingly beating out Scala’s 9%, a surprising feat for a lisp-variant.... Scala vs. Clojure - DZone Performance @Daniel: Sorry for confusion. You'll gain But for some, and for some parts of many others, it's a devastating loss. Scala is functional in the broadest sense of the word: It has immutable constructs. Marketing Blog. Clojure may appear to be simple. "Immutability as the default" is the primary reason people pick Clojure over the competition. How do I generate random integers within a specific range in Java? Well, thanks for all of the insights. Comments above are somewhat outdated - As of mid-2012 Clojure has closed the gap substantially it's now only about 2x Java on average. Clojure is designed such that multi-threaded programming mistakes are very hard to make. Proof? Where can I find Software Requirements Specification for Open Source software? How is interoperability with Java? Syntactically, it's also the furthest of the three languages from typical Java code. Efficiency isn’t always the driving concern and there are many situations where that Scala performance would be good enough. And I'd like to add that I do have a bit of a "soft spot" for LISP so the fact that Clojure suffers from parethesitis isn't enough to scare me away. But as a whole, it is a much slower language than Java. Sur la Performance et L'interopérabilité Java: Clojure vs. Scala j'ai déjà lu divers comptes rendus de Clojure contre Scala et tandis que je me rends compte que les deux ont leur place. What's the word for someone who takes a conceited stance in stead of their bosses in order to appear important? Scala vs Java. I'd say Scala is a pretty clear winner and Clojure is significantly slower--unless the Clojure test was poorly written. Though app performance depends highly on the nature of the app, let’s consider an Android application for comparison of JVM languages. "Surely this is more valuable than the few ms of runtime" .. That depends on the scale of the data. * dalvik (android's JVM) got a JIT compiler in 2.2 version in 2010. Just because both use a bytecode does not mean the implementations will have even remotely comparable performance. A Java class is a class to Scala, and a Scala class is a class to Java. SVN claims to be "CVS done right". Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks. How are you using Clojure? Join the DZone community and get the full member experience. A: That all depends. He says that Scala is a "scripting language embedded in Java", which I don't buy. 8 replies Clojure. Scala vs Clojure: Performance (Speed) Scala is fast. Or, perhaps, more seamlessly. Caught someone's salary receipt open in its respective personal webmail in someone else's computer. Scala gives you a somewhat bloated code-size, but in return you get about than 50% more performance out of your system. And the results are not encouraging. So I'd go with Scala on both these accounts. people claiming Clojure as a skill – surprisingly beating out Scala’s 9%, a surprising feat for a lisp-variant. That said, it's pretty easy to submit anything--it's all open source. Most of a … Why is the expense ratio of an index fund sometimes higher than its equivalent ETF? Any more thoughts/details on this? I think either language will be fast enough for you. Thanks for contributing an answer to Stack Overflow! How to make sure that a conference is not a scam when you are invited as a speaker? As both Scala and Java are essentially class-based languages, they interoperate more easily. Problems might arise when it comes to Scala's singletons or Java's static members, particularly when there's a framework involved expecting things to work in a certain way. Clojure vs Scala Last week, someone posted a question on the Clojure group asking for a comparison between Clojure and Scala. Mais ce n’est pas le cas, même si vous le pensez. Syntactically, it's also the furthest of the three languages from typical Java code. Java is compiled JIT (except on mobile devices*) whereas Python is interpreted. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Join Stack Overflow to learn, share knowledge, and build your career. But then again, Scala has a very flexible type system. Clojure is about as Object-Oriented as Scala is Functional. Why do jet engine igniters require huge voltages? Joy of Clojure - Questions. The new Scala books are here!!! Those things exist in Clojure for interoperability with Java, but classes and objects are clearly not main features of Clojure. Although Scala's static typing would normally translate into a speed advantage over Clojure's duck typing, Clojure does support type hinting which can speed up code considerably. Rather than waiting for functional features to appear in the JDK, many developers are switching to more functional-friendly JVM languages, such as Scala, Kotlin, and Clojure. I learned scheme first, then haskell, then (now) clojure. Imagine a very common situation — you need to write a string-processing function. Ask Question Asked 8 years, 5 months ago. Table of Content. Ni l’un ni l’autre ne se trouve bien en dessous. I have already read various accounts of Clojure vs. Scala and while I realize that both have their place. Developer On the other hand, if you don't care about OO and you want to learn "pure" functional programming, try Clojure. With the present JVM Scala has an advantage on the account of being statically typed, as JVM support for dynamic typing -- reflection -- is slow. How do I convert a String to an int in Java? There are plenty of opportunities for application level code for which that does not matter: but also plenty of framework / multithreading/processing intensive code bases where that would be a liability. that Clojure can generate code very similar to statically typed languages using type hints. Scala et Clojure s’assoient facilement au-dessus de Java. Heck! This answer sheds good light on the true differences and strengths/weaknesses of the two. Please justify. 5 replies Scala. Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. Why not try them both? Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. A comparison of Clojure and Scala for implementing a web API. a few ms is fine for a few records. Firstly understand that Racket and Clojure are both in the Lisp family but were created and developed for very different reasons. It is pretty difficult to optimize the byte code in Clojure and hence the performance of Scala is better in terms of byte code. When comparing Python and Java, it seems a bit unreasonable to blame the language for the speed difference. Why not Clojure/Haskell/Scala? Benefits? Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. Scala is more likely to be "the next Java", while it's hard to imagine that Lisp will finally take off after not doing so for over 50 years. Clojure wins because: Scala. Scala on the other hand is much closer to Java. There are a few considerations that I haven't acquired a complete explanation on when it comes to comparing both Clojure with Scala: 1.) Creating getters and setters following the Java Bean convention requires an annotation. Clojure is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. But both Scala and Clojure are JVM languages so they should have similar performance. Dynamic languages that need to stay interoperable with a static languages like Java are, @julkiewicz - it is simply not true that dynamic languages are. Clojure vs Racket: What are the differences? How would a theoretically perfect language work? Some people may even ask why? Clearly you haven't used Clojure. I'd go for Scala, because it is object oriented but also allows you to learn functional programming (if you're interested in that). Look at, Huh. LinkedIn shows 42% growth (year over year?) One thing about Clojure is the language seems very simple. Scala or Clojure Functional Programming best practices. 17 replies Clojure. A quick perusal of eFinancialCareers technology jobs confirms the results of this survey - there just aren’t that many roles for functional languages. Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this. The Computer Language Benchmark Game sheds little light on Clojure's true resource costs. But it isn't, even if you think it is. No Clojure data structures are employed. Some may even say that Scala is infact a part of Java itself, then why this scala vs java comparison? Clojure vs Scala - anecdote Showing 1-22 of 22 messages. See the original article here. In fact, one Scala feature which must be implemented through the same techniques, structural types, is often warned against for this very reason. clojure vs scala. If your code is time-critical or space-critical throughout, stick to Java. Calling Scala from Java is most of the time straightforward, but for example Scala's companion objects requires knowing how they are compiled to bytecode. 6. It's not always true that a language written in the JVM will perform at top speed. People asked about a few other languages as well, so let's get them out of the way first. For most of most applications, this is a big win. "scripting language embedded in Java". All I have read so far is that Scala has native collections types that make it a bit clumsy to integrate with a large Java code-base, whereas Clojure follows a simple Iterable/Iterator-centric way to inter-operate with Java classes.
