Why do people like Clojure?

One big reason why running on the JVM was a success factor for Clojure was that in Java, concurrency is hard. Concurrency plus mutability is hard. And idiomatic Java works by mutating state. A language where immutability is idiomatic can be appealing even to somebody who knows that java.

Why does Clojure exist?

Rich Hickey developed Clojure because he wanted a modern Lisp for functional programming, symbiotic with the established Java platform, and designed for concurrency. For this purpose, Clojure provides several mutable reference types, each having well-defined semantics for the transition between states.

Why does Clojure have so many parentheses?

The fundamental reason is that Clojure was designed as a homoiconic language, i.e. code is expressed in the core data structures of the language. All Lisps share this property, but few other languages do. As a result, the entire language design of Lisps is strongly influenced by this decision.

What are advantages of Clojure?

Clojure offers many useful modern features, including software transactional memory (STM), persistent immutable data structures, interactive programming through a read-eval-print loop (REPL), strong JVM integration by compiling to bytecode, simple Java API calls, and much more.

Why is Clojure bad?

I switched to F# and “get” FP much better now. I’d know what I was doing if I ever switched back to Clojure. But I have no good reason to personally, and all the aforementioned reasons not to professionally. No language I’ve used is exempt from the possibility of people writing bad code evoking those questions.

Is clojure readable?

Code = Data = Data Viz There’s a famous Lisp aphorism that ‘code is data’, meaning that the syntax for Lisp is a notation for data structures that can easily be manipulated by the language (after all, LISP stands for LISt Processing). In the case of Clojure, these data structures are lists, vectors and maps.

What is a vector in Clojure?

A Vector is a collection of values indexed by contiguous integers. A vector is created by using the vector method in Clojure.

What kind of language is Clojure?

functional programming language
Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures.

Is Clojure still relevant?

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.

How functional is Clojure?

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.
