Start Crystal from zero. Set up your environment, learn the core syntax, and write your first working programs with confidence.
Go beyond the basics of Crystal: data types, collections, error handling, and the standard library you reach for every day.
Level up your Crystal. Write idiomatic, well-structured code and solve real problems with the right tools and patterns.
Master advanced Crystal: deep language features, metaprogramming, internals, and the techniques senior engineers rely on.
Design with objects in Crystal: classes, inheritance, composition, and SOLID principles for maintainable systems.
Apply functional techniques in Crystal: pure functions, immutability, higher-order functions, and composition.
Write fast, correct concurrent Crystal: threads, async, synchronization, and avoiding race conditions and deadlocks.
Ship reliable Crystal: unit and integration tests, mocking, and test-driven development workflows.
Implement and apply the essential data structures and algorithms in Crystal, with complexity analysis and interview-style problems.
Apply battle-tested design patterns in Crystal to write flexible, maintainable, and extensible software.
Make Crystal fast: profiling, memory, algorithmic improvements, and the optimization techniques that matter in production.
