Differences

The following are some key differences between Lua and Crystal.

Characteristic	Lua	Crystal
Syntax	Lua has a simple and lightweight syntax with a focus on simplicity and ease of use.	Crystal has a syntax similar to Ruby, with a strong focus on readability and expressiveness.
Paradigm	Lua is a multi-paradigm language that supports procedural, functional, and object-oriented programming.	Crystal is a statically-typed, object-oriented language with a syntax inspired by Ruby.
Typing	Lua is dynamically typed, allowing for flexible and dynamic programming.	Crystal is statically typed, providing type safety and compile-time checks.
Performance	Lua is known for its fast and efficient performance, especially in embedded systems and game development.	Crystal aims to combine the expressiveness of Ruby with the performance of statically-typed languages like C.
Libraries and frameworks	Lua has a smaller ecosystem of libraries and frameworks compared to more popular languages, but it has a strong focus on embedding and extending.	Crystal has a growing ecosystem of libraries and frameworks, leveraging the existing Ruby ecosystem.
Community and support	Lua has an active and supportive community, with resources and forums available for assistance.	Crystal has a smaller but growing community, with active development and community support.
Learning curve	Lua has a relatively low learning curve, with a simple syntax and minimalistic design.	Crystal has a moderate learning curve, especially for developers familiar with Ruby or statically-typed languages.
