Scala; TL;DR. Scala & Clojure run on the JVM and compete for a replacement for Java. So, perhaps I'll pick both and do a fast-walk with them :-). Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks. To learn more, see our tips on writing great answers. 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. 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. You would be hard-pressed to pick two better languages, though I like Ruby also. Asking for help, clarification, or responding to other answers. I already have Python at my side for doing quick-and-dirty tasks. 2-25x slower than Java, 2-30x more memory and code size is generally larger than Java. People asked about a few other languages as well, so let's get them out of the way first. There you go. I did a lot of self-study coding, got some experience with Parallel Programming Models: Actors, Software Transactional Memory, Data Flow. Dynamic languages that need to stay interoperable with a static languages like Java are, @julkiewicz - it is simply not true that dynamic languages are. It isn't, but it is expressive. people claiming Clojure as a skill – surprisingly beating out Scala’s 9%, a surprising feat for a lisp-variant.... Scala vs. Clojure - DZone Performance So I'd go with Scala on both these accounts. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. One thing about Clojure is the language seems very simple. 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. Benefits? So, if Clojure is significantly slower: I'd like to know sooner rather than later. How do I read / convert an InputStream into a String in Java? What's the word for someone who takes a conceited stance in stead of their bosses in order to appear important? Why did the design of the Boeing 247's cockpit windows change for some models? How do I generate random integers within a specific range in Java? Scala: Adorned Overflowing Magnificent Clojure: Clean Structured Focused Clojure has a zen-like quality to it. And since Scala author Martin Odersky wrote Sun's Java compiler, I kinda think no balls have been dropped on the Scala side, either. The language, also, can be to blame. Clearly you haven't used Clojure. Say, the input string contains a = character, and you have to grab everything to the left of it, drop all non-letter characters, and change the case of all letters inside. Ask Question Asked 8 years, 5 months ago. I'd go for Scala, because it is object oriented but also allows you to learn functional programming (if you're interested in that). Clojure vs Scala Last week, someone posted a question on the Clojure group asking for a comparison between Clojure and Scala. Calling Java code and extending Java classes/interfaces works the same way as calling Scala code. Another example: Run Java, Clojure 1.3, Clojure 1.4 alpha1, and Clojure 1.4 alpha3 versions of all of the benchmark programs. functional + object oriented + actors + familiar syntax; this seems great until you realize how complex it makes things. Syntactically, it's also the furthest of the three languages from typical Java code. You can of course call into this component from Java, but what you are not going to want to do is try to consume a Scala API intended for use by Scala programs from Java. multiply by hundreds of millions .. It seems that the benchmark does covers Clojure now (OP's remark is one year old). Scala gives you a somewhat bloated code-size, but in return you get about than 50% more performance out of your system. I have already read various accounts of Clojure vs. Scala and while I realize that both have their place. Four of the five top paying languages are the functional programming languages Clojure, F#, Scala and Elixir. Clojure is functional and pure, it protects you. But then again, Scala has a very flexible type system. Scala has been said to be Java done right. You will not want to mix and match much. If your code is time-critical or space-critical throughout, stick to Java. I learned scheme first, then haskell, then (now) clojure. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. But, I know that Scala is fast (based on multiple personal accounts). Well, thanks for all of the insights. Though app performance depends highly on the nature of the app, let’s consider an Android application for comparison of JVM languages. The November 2010 issue of PragPub discusses Clojure-Java interoperability. On the other hand, if you don't care about OO and you want to learn "pure" functional programming, try Clojure. But both Scala and Clojure are JVM languages so they should have similar performance. Scala vs Java. Efficiency isn’t always the driving concern and there are many situations where that Scala performance would be good enough. But it's clear that Lisp is on its own unique level of abstraction, and Clojure is fairly simple, so Scala + Clojure won't be that much harder than just (the rather complex) Scala and I'm sure you will be glad you did it. Or, perhaps, more seamlessly. Making statements based on opinion; back them up with references or personal experience. Scala vs Clojure: Performance (Speed) Scala is fast. You can implement an interface, extend a class, declare private and static functions, etc. Clojure is designed such that multi-threaded programming mistakes are very hard to make.
