Differences

The following are some key differences between Groovy and Crystal.

Characteristic	Groovy	Crystal
Syntax	Groovy has a syntax similar to Java with additional features like closures and dynamic typing.	Crystal has a syntax inspired by Ruby with a focus on simplicity and readability.
Paradigm	Groovy is a multi-paradigm language that supports both object-oriented and functional programming.	Crystal is a statically-typed, object-oriented language with a focus on simplicity and performance.
Typing	Groovy is dynamically typed, allowing for flexible and concise code.	Crystal is statically typed, providing better performance and compile-time type checking.
Performance	Groovy is slower than Java due to its dynamic nature and runtime overhead.	Crystal is designed for performance and can be as fast as C or C++.
Libraries and frameworks	Groovy has a wide range of libraries and frameworks available, including Grails and Spock.	Crystal has a smaller ecosystem compared to Groovy, but it can interoperate with existing C libraries.
Community and support	Groovy has an active community and good support from its developers.	Crystal has a growing community, but it may have less support and resources compared to more established languages.
Learning curve	Groovy has a relatively low learning curve, especially for Java developers.	Crystal has a moderate learning curve, with similarities to Ruby and other C-style languages.
