== Description ==

Although resembling the Ruby language in syntax, Crystal compiles to much more efficient native code using an [[LLVM]] backend, at the cost of precluding the dynamic aspects of Ruby. The advanced global type inference used by the Crystal compiler, combined with [[union type]]s, gives it more the feel of a higher-level scripting language than many other comparable programming languages. It has automated garbage collection and offers a [[Boehm garbage collector|Boehm collector]]. Crystal possesses a macro system and supports generics as well as method and operator overloading. Its concurrency model is inspired by [[communicating sequential processes]] (CSP) and implements lightweight fibers and channels (for interfiber communication), inspired by [[Go (programming language)|Go]].<ref name = "go multithread">{{cite web | url=https://forum.crystal-lang.org/t/crystal-multithreading-support/6622/19 | title=Crystal multithreading support | date=23 February 2024 }}</ref>
