Crystal is a general-purpose, concurrent, multi-paradigm, object-oriented programming language.
With syntax heavily inspired by the language Ruby, it is a compiled language with built-in static type-checking, but specifying the types of variables or method arguments is generally unneeded. This adds the benefit of a shallower learning curve.
The language also offers a powerful macro system, the compiler automatically checks for null references in compile time, a sleek concurrency model that uses green threads, as well as dedicated syntax to easily call native libraries.

Here’s our recommended tutorials to learn Crystal.
1. Language Introduction by Crystal
This course is targeted at novice Crystal programmers and conveys a basic understanding of the language’s core concepts. Prior programming experience is recommended, but not required. This course can help you learn your first programming language.
2. A First Look at Crystal Programming Language and its Ecosystem by Meraj Molla
Take your first steps with Crystal.
3. The Highs & Lows of Crystal – an Introduction to Crystal Lang by Robin Percy
Crystal Language claims to be as fast as C and as easy to learn as Ruby. Here, the author puts that assertion to the test and gives his opinion.
4. A very simple tutorial of the Crystal programming language by Andrew Garcia
