Why Clojure is better than Scala?
Therefore, what makes Clojure better than Scala is that although initially Clojure has a steeper learning curve and needs some getting-used-to, once you become a Clojure pro, the language gets out of your way and allows you to truly bend the project to your will.
What is Clojure mainly used for?
What is Clojure mainly used for? Clojure is being used extensively for processing large volumes of data. It is very well suited to data mining/commercial-AI (ie: Runa) and large scale predictions (aka WeatherBill). Clojure’s concurrency story really helps in these data heavy domains where parallel processing is simply the only answer.
What do you use Clojure for?
The necessity to Use Clojure
- It is a powerful, coherent, and simple tool consisting of a set of useful features.
- It provides a dynamic environment to interact with. ...
- It belongs to the Lisp family of languages adding the features code as data and macrosystem to Clojure.
What is Clojure bad at?
What is clojure bad at? There are things that Clojure wasn’t designed for, and isn’t intended for. To complain that Clojure is “bad” at type-checking is a bit like worrying that your car doesn’t dance. Clojure is built on the philosophy that you should use other strategies to get the effects of reliability that static typing promises.
Is Clojure fully functional?
Clojure is a functional programming language. It provides the tools to avoid mutable state, provides functions as first-class objects, and emphasizes recursive iteration instead of side-effect based looping.
Is Clojure still used?
Clojure (still) for Start-ups While more large companies are adopting Clojure than ever, the sweet spot is still the smaller companies of less than 100 employees. The reasons that start-ups choose Clojure are many and variegated: Leverage - small effort, big result.
Is Clojure practical?
Clojure is a practical and pragmatic language. It helps to organize a fast and efficient software development process.
Does Netflix use Clojure?
Clojure is a dynamic programming language that has been growing in popularity in recent years, seeing adoption from many developers and companies. Big names such as Adobe, Amazon, Apple, Facebook, and Netflix (among many others) all use Clojure somewhere in their tech stacks.
Why is Clojure not popular?
Clojure may not find much popularity since it lacks sufficient Clojure-based libraries and frameworks, compared to other applications worth consideration. The lisp syntax of Clojure is also more difficult to read, and therefore could stir being unfamiliar with the tool.
Should I learn rust or Clojure?
The big difference between the two, and why I think they complement each other nicely, is that Clojure is optimized for development, and does its best at runtime, but Rust is optimized for runtime, and tries its best at development.
Does Walmart use Clojure?
Walmart used Clojure to create a robust data management system that supports over 5,000 stores and integrates online and mobile data. Learn how Walmart is running Clojure at Scale.
Is Clojure used in AI?
It was favored especially among the artificial intelligence researchers. Clojure, the Lisp of today, is often used with web development, with integrations to both Java and JavaScript ecosystems.
Do companies use Clojure?
A quick scan of various job sites shows Clojure positions at companies like Walmart, Facebook, Staples, Consumer Reports, Salesforce, and Amazon. It doesn't get much more mainstream than that.
Is Clojure good for Microservices?
Nubank started with a microservices-based architecture using Clojure as the main language, Datomic for the database, and Kafka for messaging. The architecture is based on Alistair Cockburn's Hexagonal Architecture and is largely immutable, with most of the mutable state managed through Datomic.
What is Clojure best for?

Is Clojure faster than Java?
It was found that Clojure ran several times slower than Java in all conducted experiments.
What is a clojure function?
Clojure is a functional language . Functions are first-class and can be passed-to or returned-from other functions. Most Clojure code consists primarily of pure functions (no side effects), so invoking with the same inputs yields the same output.
What is identity in Clojure?
In Clojure, this is the identity function. By itself, identity is not very useful, but it is sometimes necessary when working with higher-order functions. (source identity) 5) Define a function always-thing which takes any number of arguments, ignores all of them, and returns the number 100.
Does Clojure have expressions?
Many languages have both statements, which imperatively do something and do not return a value, and expressions which do. Clojure has only expressions that return a value. We’ll see later that this includes even flow control expressions like if.
Does Clojure slurp use URL?
In fact, the Clojure slurp function interprets its argument as a URL first before trying it as a file name. Write a simplified http-get:
An introduction to Object-Oriented Programming
Object-Oriented Programming has been the go-to approach in software development for the last couple of decades. Its origins can be traced back to 1961 in the works of Ole-Johan Dahl and Kristen Nygaard as well as the programming language Smalltalk, created by Alan Kay in 1980.
Overcoming the Paradigm
Unfortunately, to paraphrase philosopher Thomas Khun, paradigms have their limits. The longer you spend working within a paradigm, the more you see the cracks on the wall. The more you grow as a developer, the more you push the boundaries of a paradigm.
Where is Clojure used?
Clojure is well known as the backend language of Brazil’s Nubank, the biggest digital bank in the world. According to the latest stats, about 700 Clojure developers are part of Nubank’s development team.
Why Functional Programming?
Functional programming proponents believe that their approach creates cleaner code that’s easier to maintain and requires less debugging.
What is the advantage of Clojure?
( most of the time) The biggest advantage of Clojure is that it can be so flexible and dynamic under a powerful system like JVM.
What is Clojure programming?
Clojure is a functional programming language, that runs on JVM ( Java Virtual Machine ), CLR ( Common Language Runtime) and JavaScript platforms. I was considering to learn Lisp for a long time. The reason for this is that my lecturer Chris Stephenson had strong discourses on functional programming and he was using Racket (a Lisp dialect) ...
What is a clojure script?
ClojureScript is a compiler for Clojure that targets JavaScript. So you write Clojure code and finally have an optimized JavaScript code. When you work on frontend and backend, you use a single language and thus you have the advantage of motivation and time.
Why is clojure written on JVM?
The creator of the language Rich Hickey has a very pragmatic and strategic reason for writing Clojure on JVM. As it was written on JVM, Clojure gives access to all available Java ( or any JVM language) libraries and their frameworks. So you can call Java code from Clojure code, or vice versa.
Why is Clojure immutable?
He developed the Clojure which is immutable by default for concurrent systems, because this work gets harder to be carried out due to this kind of difficulties ( mutable data problems ). The fact that immutable data will not change when it is sent to another thread so we don’t have to worry about the state of the data.
What is the community of Clojure?
Clojure community consists of really cute, helpful and generally senior and experienced ladies and gentlemen. Of course, it is not as big as the community of other languages. It has a modest, small and sympathetic volume, because it is a niche technology ecosystem.
What is the biggest bet of Clojure?
One of the biggest bet of Clojure is that it was designed in a manner that it makes writing concurrent programs easy and entertaining as well as provides an opportunity for a less amount of error at the same time.
What is Clojure's purpose?
Clojure advocates immutability and immutable data structures and encourages programmers to be explicit about managing identity and its states. This focus on programming with immutable values and explicit progression-of-time constructs is intended to facilitate developing more robust, especially concurrent, programs that are simple and fast. While its type system is entirely dynamic, recent efforts have also sought the implementation of a dependent type system.
Why was Clojure created?
Clojure was created from the ground up to embrace its host platforms as one of its design goals and thus provides excellent language interoperability with Java:
What is Clojure programming language?
Clojure ( / ˈkloʊʒər /, like closure) is a dynamic and functional dialect of the Lisp programming language on the Java platform. Like other Lisp dialects, Clojure treats code as data and has a Lisp macro system. The current development process is community -driven, overseen by Rich Hickey as its benevolent dictator for life (BDFL).
How long did Hickey work on Clojure?
Hickey spent about 2½ years working on Clojure before releasing it publicly, much of that time working exclusively on Clojure with no outside funding. At the end of this time, Hickey sent an email announcing the language to some friends in the Common Lisp community.
Why did Rich Hickey create Clojure?
Rich Hickey developed Clojure because he wanted a modern Lisp for functional programming, symbiotic with the established Java platform, and designed for concurrency. Clojure's approach to state is characterized by the concept of identities, which are represented as a series of immutable states over time.
What is a REPL in Clojure?
As a Lisp dialect, Clojure supports functions as first-class objects, a read–eval–print loop (REPL), and a macro system. Clojure's Lisp macro system is very similar to that of Common Lisp with the exception that Clojure's version of the backquote (termed "syntax quote") qualifies symbols with their namespace.
Is Clojure a Lisp?
Clojure's reader supports literal syntax for maps, sets and vectors in addition to lists, and these are compiled to the mentioned structures directly. Clojure is a Lisp-1 and is not intended to be code-compatible with other dialects of Lisp, since it uses its own set of data structures incompatible with other Lisps.

Why Functional Programming?
- Functional programming proponents believe that their approach creates cleaner code that’s easier to maintain and requires less debugging. For example, if you need to transform uppercase “A” to lowercase “a” you write a function that takes “A” and outputs an “a.” You don’t change the original data, you just use it to output something else. This avoids the problem of inadvertently transfor…
