Get better at programming through fun, rewarding coding exercises that test your understanding of concepts with Exercism.
Given a number determine whether or not it is valid per the Luhn formula.
Correctly determine change to be given using the least number of coins
Find the difference between the square of the sum and the sum of the squares of the first N natural numbers.
Extends Lisp's code-as-data system to vectors and maps, and has a powerful macro system.
Clojure's primary programming interface is the Read-Eval-Print-Loop (REPL).
Allows avoiding mutable state, provides functions as first-class objects, and emphasizes recursion.
Doesn’t force programs to be referentially transparent, and doesn’t strive for 'provable' programs.
Supports sharing changing state between threads in a synchronous and coordinated manner.
Shares the JVM type system, GC, threads etc. Compiles all functions to JVM bytecode.
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.Learn more about mentoring
