Key differences between Objective_C and Crystal

CharacteristicObjective_CCrystal
SyntaxObjective-C uses a syntax similar to C with added features for object-oriented programming.Crystal has a syntax inspired by Ruby, with a focus on simplicity and readability.
ParadigmObjective-C supports both procedural and object-oriented programming paradigms.Crystal is a statically-typed, object-oriented language that also supports metaprogramming.
TypingObjective-C is a dynamically-typed language.Crystal is a statically-typed language with type inference.
PerformanceObjective-C has good performance and is often used for iOS and macOS development.Crystal aims to have similar performance to C, thanks to its static typing and LLVM backend.
Libraries and frameworksObjective-C has a wide range of libraries and frameworks, especially for iOS and macOS development.Crystal has a growing ecosystem of libraries and can also use existing C libraries.
Community and supportObjective-C has a large community and is well-supported, especially for iOS and macOS development.Crystal has a smaller but active community with good support available.
Learning curveObjective-C has a moderate learning curve, especially for developers familiar with C.Crystal has a relatively low learning curve, especially for developers familiar with Ruby.
