The Crystal Programming Language
Crystal is a general-purpose, object-oriented programming language. With syntax inspired by Ruby, it’s a compiled language with static type-checking. Types are resolved by an advanced type inference algorithm.
Crystal is a programming language with a syntax similar to Ruby, designed for performance and efficiency. It combines the ease of writing code with the speed of execution, making it an attractive option for developers looking for a balance between productivity and performance.
