Key differences between COBOL and Fsharp

CharacteristicCOBOLFsharp
SyntaxCOBOL uses a verbose and English-like syntax with a fixed format.F# uses a concise and expressive syntax inspired by ML languages.
ParadigmCOBOL is primarily procedural and imperative.F# is a multi-paradigm language that supports functional, imperative, and object-oriented programming.
TypingCOBOL is statically typed with weak typing.F# is statically typed with strong typing.
PerformanceCOBOL is known for its efficiency and performance in handling large-scale business applications.F# is a high-performance language that can leverage the power of the .NET runtime.
Libraries and frameworksCOBOL has a limited set of libraries and frameworks compared to modern languages.F# has access to a wide range of libraries and frameworks in the .NET ecosystem.
Community and supportCOBOL has a smaller and more specialized community with limited support.F# has an active and growing community with good support from Microsoft and the F# Software Foundation.
Learning curveCOBOL has a steep learning curve due to its verbose syntax and outdated concepts.F# has a moderate learning curve, especially for developers familiar with functional programming.
