Key differences between Crystal and Ruby

CharacteristicCrystalRuby
SyntaxCrystal has a syntax similar to Ruby, but with some differences. It has a more strict and static type system.Ruby has a more flexible and dynamic syntax compared to Crystal. It allows for more expressive and concise code.
ParadigmCrystal is a statically-typed, compiled language that supports object-oriented and imperative programming paradigms.Ruby is a dynamically-typed, interpreted language that supports multiple programming paradigms including object-oriented, functional, and procedural.
TypingCrystal has a static type system, which means variables must be declared with their types and type checking is done at compile-time.Ruby has a dynamic type system, which means variables do not need to be declared with their types and type checking is done at runtime.
PerformanceCrystal is known for its high performance as it compiles to native code. It can be as fast as C or C++.Ruby is generally slower compared to Crystal as it is an interpreted language. However, it has improved performance with the introduction of Just-in-Time (JIT) compilation in recent versions.
Libraries and frameworksCrystal has a smaller ecosystem compared to Ruby, but it can still leverage some Ruby libraries through its compatibility with Ruby's C API.Ruby has a vast ecosystem with a wide range of libraries and frameworks available for various purposes.
Community and supportCrystal has a smaller community compared to Ruby, but it is growing steadily. It has an active community that provides support and contributes to its development.Ruby has a large and active community with extensive support and resources available. It has been around for a long time and has a mature ecosystem.
Learning curveCrystal has a relatively steeper learning curve compared to Ruby due to its stricter type system and additional features.Ruby has a relatively easier learning curve compared to Crystal. Its syntax is more forgiving and it has a simpler type system.
