Join the Racket Track
Racket is a programming language that can be used to build programming languages. Racket is based on Scheme and LISP but it's got some really neat innovations. If you're learning there's some great education support in How to Design Programs and Realm of Racket.

About Racket

#lang racket

(provide hello)

(define (hello [name "World"])
  (string-append "Hello, " name "!"))

"Racket (formerly named PLT Scheme) is a general purpose, multi-paradigm programming language in the Lisp/Scheme family. One of its design goals is to serve as a platform for language creation, design, and implementation. The language is used in a variety of contexts such as scripting, general-purpose programming, computer science education, and research." - Wikipedia

You can learn the basics of Racket through a coule of books. Start by checking out How to Design Programs or the slightly less formal but enjoyable Realm of Racket.

The official language website can be found at http://racket-lang.org/ and the source code is at https://github.com/racket/racket/. You can find the community on twitter, email or slack.

Exercism is a great website

What I like about it is that I am able to solve the challenges in a TDD way working in a environment that I am familiar (my own PC not a browser IDE) and the cherry on the top of the cake is that I have access to code reviews.

Relaxed. Encouraging. Supportive.

I love Lisp, functional programming, and language-oriented programming.

I'm on the 'Language-Oriented Programming' paradigm from Racket. Love to program, love to help.

Robert Postill The blog I hardly ever post to :|

I've been programming for a while and I love sharing my knowledge and being taught new things :)
Fun. Challenging. Interesting
