Differences

The following are some key differences between Ruby and Crystal.

Characteristic	Ruby	Crystal
Syntax	Ruby has a more flexible and expressive syntax compared to Crystal.	Crystal has a syntax similar to Ruby, but with stricter type annotations.
Paradigm	Ruby is a dynamically-typed, object-oriented language with support for functional programming.	Crystal is a statically-typed, object-oriented language with support for metaprogramming.
Typing	Ruby is dynamically-typed, meaning that variable types are determined at runtime.	Crystal is statically-typed, meaning that variable types are checked at compile-time.
Performance	Ruby is generally slower compared to Crystal due to its dynamic nature.	Crystal is designed to be statically compiled and can achieve performance similar to C.
Libraries and frameworks	Ruby has a vast ecosystem of libraries and frameworks, including Ruby on Rails.	Crystal has a smaller ecosystem compared to Ruby, but can also use some Ruby libraries.
Community and support	Ruby has a large and active community with extensive documentation and support.	Crystal has a growing community, but it is smaller compared to Ruby.
Learning curve	Ruby has a relatively gentle learning curve, especially for beginners.	Crystal has a steeper learning curve compared to Ruby, mainly due to its stricter typing and metaprogramming features.
