How to use this tool?

This free online converter lets you convert code from Crystal to Haskell in a click of a button. To use this converter, take the following steps -

  1. Type or paste your Crystal code in the input box.
  2. Click the convert button.
  3. The resulting Haskell code from the conversion will be displayed in the output box.

Examples

The following are examples of code conversion from Crystal to Haskell using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Key differences between Crystal and Haskell

CharacteristicCrystalHaskell
SyntaxCrystal 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.
ParadigmCrystal supports both object-oriented and functional programming paradigms.Haskell is a purely functional programming language.
TypingCrystal has static typing with type inference.Haskell has static typing with strong type inference.
PerformanceCrystal 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 frameworksCrystal 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 supportCrystal has a smaller community compared to languages like Haskell, but it is growing.Haskell has a large and active community with strong support.
Learning curveCrystal 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.
