Key differences between Fortran and Crystal

CharacteristicFortranCrystal
SyntaxFortran uses a fixed-format syntax with strict column-based rules.Crystal uses a Ruby-like syntax with a focus on readability and expressiveness.
ParadigmFortran is primarily a procedural programming language with support for object-oriented programming.Crystal is a statically-typed, compiled language that combines features from object-oriented and functional programming.
TypingFortran is statically-typed with support for strong typing.Crystal is statically-typed with support for strong typing and type inference.
PerformanceFortran is known for its high performance and efficiency in scientific and numerical computing.Crystal aims to provide a balance between performance and developer productivity.
Libraries and frameworksFortran has a wide range of libraries and frameworks for scientific and numerical computing.Crystal has a growing ecosystem of libraries and frameworks, but it may not have as extensive support as Fortran.
Community and supportFortran has a long-standing community and strong support in the scientific and numerical computing fields.Crystal has a smaller but growing community with active support from its developers and community members.
Learning curveFortran has a steeper learning curve due to its strict syntax and focus on scientific and numerical computing.Crystal has a relatively gentle learning curve, especially for developers familiar with Ruby or similar languages.
