Join the Scheme Track
Programming languages should be designed not by piling feature on top of feature, but by removing the weaknesses and restrictions that make additional features appear necessary.

About Scheme

(let ((quine '((lambda (q) `(,q ',q))
               '(lambda (q) `(,q ',q)))))
  (equal? quine (eval quine)))

Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language invented by Guy Lewis Steele Jr. and Gerald Jay Sussman. It was designed to have an exceptionally clear and simple semantics and few different ways to form expressions. A wide variety of programming paradigms, including functional, imperative, and message passing styles, find convenient expression in Scheme.

A tremendous learning opportunity to explore the depth of your own knowledge

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.

Relaxed. Encouraging. Supportive.

I started in the Lisp family with Common Lisp but I love the elegant simplicity of Scheme and how it enables Functional Programming.
Fun. Challenging. Interesting

I have fallen in love with Scheme in a very short period of time. I am looking forward to helping build this into a robust and healthy track ;)

Get started with the Scheme track. As with everything on Exercism, it's 100% free!
