Differences

The following are some key differences between Haskell and Crystal.

Characteristic	Haskell	Crystal
Syntax	Haskell has a unique syntax that is based on mathematical notation and is known for its strong type inference.	Crystal has a syntax similar to Ruby, with some additional features like static typing.
Paradigm	Haskell is a purely functional programming language.	Crystal is a statically typed, object-oriented programming language with some functional programming features.
Typing	Haskell has strong static typing with type inference.	Crystal has static typing with type inference, but also allows for dynamic typing when needed.
Performance	Haskell is known for its high performance, especially in terms of memory usage.	Crystal aims to have a similar performance to statically typed languages like C or C++, but with a more expressive syntax.
Libraries and frameworks	Haskell has a growing ecosystem of libraries and frameworks, although it may not have as many options as more popular languages.	Crystal has a smaller ecosystem of libraries and frameworks compared to more established languages, but it is growing.
Community and support	Haskell has a dedicated and active community, with good support available through forums, mailing lists, and online resources.	Crystal has a smaller community compared to more popular languages, but it is growing and has active support channels.
Learning curve	Haskell has a steep learning curve due to its unique syntax and functional programming concepts.	Crystal has a relatively low learning curve, especially for developers familiar with Ruby or other similar languages.
