About Crystal

Crystal is a compiled language that is currently in the alpha stages of development. These are some of the language's goals:

  • Ruby-inspired syntax.

  • Statically type-checked but without having to specify the type of variables or method arguments.

  • Be able to call C code by writing bindings to it in Crystal.

  • Have compile-time evaluation and generation of code, to avoid boilerplate code.

  • Compile to efficient native code.

Exercism is a great website

Exercism is a great website where I was able to have some very interesting challenges.
