Key Features of Clojure


Clojure
Image

Lisp

Extends Lisp's code-as-data system to vectors and maps, and has a powerful macro system.

Image

Dynamic

Clojure's primary programming interface is the Read-Eval-Print-Loop (REPL).

Image

Functional

Allows avoiding mutable state, provides functions as first-class objects, and emphasizes recursion.

Image

Practical

Doesn’t force programs to be referentially transparent, and doesn’t strive for 'provable' programs.

Image

Concurrent

Supports sharing changing state between threads in a synchronous and coordinated manner.

Image

JVM Hosted

Shares the JVM type system, GC, threads etc. Compiles all functions to JVM bytecode.

Get mentored the Clojure way

Every language has its own way of doing things. Clojure is no different. Our mentors will help you learn to think like a Clojure developer and how to write idiomatic code in Clojure. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Clojure - they'll help you discover the things you don't know that you don't know.
