In nature, a crystal is a substance with molecules arranged in a lattice. Some substances, such as halide crystals, are composed of separate elements arranged perfectly to make them stronger than they would be alone. Crystal, the language, aims for a similar solution, marrying an object-oriented base with functional elements. Crystals grow by aggregating material from their environment, and the Crystal language attempts to take the best features of other languages that have gone before, such as static typing, automated garbage collection, generic support, concurrency, and a macro system. If you're a fan of Ruby, it's worth checking out.
Come and get it!
Programming Crystal: Create High-Performance, Safe, Concurrent Apps
Explore the building blocks and design of the language and how you can use the Crystal tool-chain to build and manage powerful applications. Harness the power of the macro system, as well as how to work with fibers and channels, making concurrency as easy as possible. Learn how to use the Kemal web framework and access databases and how to tap the potential of existing Crystal libraries. Find the spot that Crystal fills in today's software world with real-world examples.
With Crystal, you can combine the best of both worlds: the high-level coding of dynamic languages and the safety and blazing performance of a natively compiled language.
