clojure vs scala performance

"Surely this is more valuable than the few ms of runtime" .. That depends on the scale of the data. 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. You don't create classes and design your project in an OO way if you're going to program in Clojure. It can get work done even faster than Java. A lazy sequence is implemented in Clojure while in Scala it is not implemented. Not so with Scala. 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.

It seems that the benchmark does covers Clojure now (OP's remark is one year old). Clojure is functional and pure, it protects you. Since my most popular blog post, by far, is my Racket vs Clojure post from three years ago, I thought it would be good to post my response here.Ten years ago, I would have said that my ideal dream language is one that provides the flexibility to program in any style. rev 2021.1.18.38333, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide, With Clojure 1.2 Clojure can call java without overhead.

Making statements based on opinion; back them up with references or personal experience. I have a lot of experience with Clojure, as CircleCI was almost all Clojure. I’d say the most important are these : Racket is an evolution of Scheme. The stats produced by the "Computer Language Benchmark Game" are about the best you're probably going to find. Any more thoughts/details on this? Regarding interop w/ Java, Scala is closer to Java but I'm sure both languages interoperate well. It's now (as of May 2010) worth loking at the latest 1.2 branch of Clojure - this includes a lot of additional support for primitive types and static typing (through various type hints and protocols). Scala or Clojure Functional Programming best practices. But both Scala and Clojure are JVM languages so they should have similar performance. Note that Clojure and Scala are two totally different types of programming languages - Clojure is a functional Lisp-like language, it is not object oriented. State change is handled by functions (for transformations) and atoms (an abstraction that encapsulates the idea of some entity having an identity). Dynamic languages that need to stay interoperable with a static languages like Java are, @julkiewicz - it is simply not true that dynamic languages are. Neither sits well underneath it. In my opinion, the features and concepts of a language (functional, OO, ...) are much more important criteria for choosing a language than the performance (of a particular implementation of that language) - altough I understand that you don't want to get trapped into a language for which there is no well-performing implementation available. Why did the design of the Boeing 247's cockpit windows change for some models? How to make sure that a conference is not a scam when you are invited as a speaker? Active 8 years, 5 months ago.

Most of a … If your code is time-critical or space-critical throughout, stick to Java. Scala et Clojure s’assoient facilement au-dessus de Java. Example? Also, Scala accepts mutable objects just fine, and some algorithms are just faster to implement with mutability. As both Scala and Java are essentially class-based languages, they interoperate more easily. For most of most applications, this is a big win. The problem is that they don't cover Clojure :(. He says that Scala is a "scripting language embedded in Java", which I don't buy. Developer It's not always true that a language written in the JVM will perform at top speed. :-). If you don't, then you should probably stay with Scala. How do I read / convert an InputStream into a String in Java? So I'd go with Scala on both these accounts. Join the DZone community and get the full member experience. Clojure vs Scala for High Performance Web API. A: That all depends. 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). after ~1 year with it, I've decided that haskell, while great, is not for me, and I'm switching over to clojure. Scala has been said to be Java done right. Clojure vs Racket: What are the differences? The language, also, can be to blame. 2-25x slower than Java, 2-30x more memory and code size is generally larger than Java. 7 replies Clojure. 15 replies Clojure. 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. your coworkers to find and share information. Clojure is a functional language in the LISP family, it's also dynamically typed. Clojure code does not necessarily have to be slower than Java or Scala. If you want to mutate transients for example and one of those is accessed from an outside thread, you get an exception. The Computer Language Benchmark Game sheds little light on Clojure's true resource costs. 7 replies 1. The November 2010 issue of PragPub discusses Clojure-Java interoperability. Would coating a space ship in liquid nitrogen mask its thermal signature? Why is the expense ratio of an index fund sometimes higher than its equivalent ETF? site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. Scala gives you a somewhat bloated code-size, but in return you get about than 50% more performance out of your system. I don't want to go with Clojure and run into this problem down the road.

To learn more, see our tips on writing great answers. Look at, Huh. I think either language will be fast enough for you. Imagine a very common situation — you need to write a string-processing function. I introduced Scala based on the promises of performance, concurrency and type safety - and conciseness (especially with XML being a native data type in Scala). You can implement an interface, extend a class, declare private and static functions, etc. However, we spent a whole lot of time with dealing accidental complexity, specifically "what type is this field" and nulls all over the place. You might say that it is Lisp done right - a bold, some would say preposterous, claim - which may turn out to be true. people claiming Clojure as a skill – surprisingly beating out Scala’s 9%, a surprising feat for a lisp-variant. Why not Clojure/Haskell/Scala? LinkedIn shows 42% growth (year over year?) My understanding is that you can use these features when you need it to get speed equivalent to writing exactly the same code in pure Java. that Clojure can generate code very similar to statically typed languages using type hints. 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. Clojure is nothing like Java. I already have Python at my side for doing quick-and-dirty tasks. With experience of the Clojure language, I believe it is possible to tell in advance whether your problem will cleave cleanly into a part that can be succinctly and adequately (in performance terms) expressed in Clojure and a part that needs doing in Java. But for some reason, it didn't occur to me that I could just use both and have them inter-operate.

Scala on the other hand is much closer to Java. Improve INSERT-per-second performance of SQLite. Performance and Scalability. A comparison of Clojure and Scala for implementing a web API. Functional programming. Clojure is about as Object-Oriented as Scala is Functional. I'm reaching the point where: if I'm not coding something in a functional fashion - why am I bothering with a scripting language embedded in Java anyway? But as a whole, it is a much slower language than Java. 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. LinkedIn shows 42% growth (year over year?) 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.
