Differences

The following are some key differences between Crystal and Haskell.

Characteristic	Crystal	Haskell
Syntax	Crystal has a syntax similar to Ruby, with some additional features like static typing.	Haskell has a unique syntax that is based on mathematical notation and is purely functional.
Paradigm	Crystal supports both object-oriented and functional programming paradigms.	Haskell is a purely functional programming language.
Typing	Crystal has static typing with type inference.	Haskell has static typing with strong type inference.
Performance	Crystal is known for its high performance and low memory usage.	Haskell is generally slower than languages like Crystal due to its lazy evaluation and purity.
Libraries and frameworks	Crystal has a growing ecosystem of libraries and frameworks, but it is not as extensive as some other languages.	Haskell has a rich ecosystem of libraries and frameworks, especially for functional programming.
Community and support	Crystal has a smaller community compared to languages like Haskell, but it is growing.	Haskell has a large and active community with strong support.
Learning curve	Crystal has a relatively low learning curve, especially for developers familiar with Ruby.	Haskell has a steep learning curve, especially for developers new to functional programming.
