Crystal Healing Course
Crystal is a compiled language that gives you Ruby-like syntax with C-level performance — and this course teaches you to use it from the ground up. You'll go from basic syntax to advanced topics like generics, macros, concurrency, and HTTP servers. By the end, you'll have the skills to build fast, type-safe, production-ready applications in Crystal.

What will I learn?
This course covers everything you need to become a proficient Crystal developer. You'll start with the language fundamentals — syntax, types, and control flow — then move into object-oriented design, collections, and iterators. From there, you'll tackle Crystal's static type system, generics, and compile-time macros. You'll learn to write concurrent programs using fibers and channels, build HTTP servers and clients, and manage file I/O. The course also covers testing with Crystal's built-in spec framework, dependency management with shards, and deploying optimized production binaries.
