Why you should switch from Ruby to Crystal

Crystal is a programming language that combines the simplicity and developer-friendly syntax of Ruby with the performance efficiency of C, offering features like static types, native C bindings, and powerful metaprogramming macros. While Ruby has been instrumental in the creation of successful startups like Twitter and Airbnb, its performance and scalability issues have driven some developers toward Crystal, which provides a similar syntax but with enhanced speed and efficiency. Crystal's web frameworks, such as Amber and Kemal, draw inspiration from popular frameworks like Rails and Sinatra, and the language excels in benchmarks against other languages like Go, Python, and Node.js. Despite its advantages, Crystal is relatively new, leading to a less mature ecosystem with fewer libraries and documentation compared to more established languages, though its growing community suggests potential for future development. Crystal's concurrency model, inspired by CSP, uses lightweight fibers for efficient execution, although parallelism support is still in development.
