What is Crystal?

Crystal's syntax is heavily influenced by Ruby, which makes it both easy to read and simple to write, especially advantageous for developers with prior Ruby experience who face a less steep learning curve. The language utilizes static type-checking to catch type-related errors early in the compilation process, effectively avoiding potential runtime problems. To keep the code clean and straightforward, Crystal includes built-in type inference, allowing programmers to often skip explicit type declarations. In this language, all types are inherently non-nilable, and variables are defined by a combination of their type and nil, enabling the compiler to check for null references before the code runs. Moreover, Crystal offers a powerful macro system tailored for metaprogramming, which provides a range of functionalities such as basic templating, AST inspection, type inspection, and the ability to run arbitrary external programs. This advanced macro system not only increases the flexibility of the language but also facilitates more dynamic code generation and manipulation, thereby enhancing the overall developer experience. Consequently, Crystal stands out as a modern programming language that balances simplicity with powerful features.
