Difference Between OCaml vs F#
OCaml is a general-purpose programming language it is an extension of Caml with object-oriented features which was developed earlier for automated theorem proving and also has formal methods software where we can say OCaml is under an ML-like type system that unifies imperative, functional, and object-oriented programming. F# is defined as a general-purpose strongly typed programming language that is used to manipulate objects which means this F# treats objects as another data type for functions to manipulate. F# also unifies or encompasses functional, imperative, and object-oriented programming methods and F# is mainly suitable for AI and machine learning-related data analysis.

Key Differences between OCaml vs F#
Following are the key differences between OCaml vs F#:
- Programming Type: OCaml is an object-oriented programming language as it allows writing code in the object-oriented style where it means it provides support of many different object-oriented concepts such as inheritance and parametric classes where this helps in designing more complex pattern in a very natural way. Whereas F# is a function-oriented programming language where allows writing code that contains lots of functions in it which means every line of code is a composable expression that are used in building basic functions, this functional language also allows to factor a problem into parts and also can be joined back together easily without the need of rewriting the code again.
- Pattern Matching: In OCaml it comes in several places where this pattern matching is a shortcut way of defining functions by case analysis and also provides a way of handling exceptions, this feature in OCaml provides a powerful control structure that has a combination of variable binding, multi-armed conditional, unification and data restructuring and sometimes it has the ability to detect non-exhaustive patterns and can warn about this to the developers. Whereas in F# the pattern matching feature is much safer and as it supports the most general form of conditional expressions where pattern matching with “union” or “choice” type is used instead of using inheritance.
- Portability: OCaml is portable as it can be run on many different platforms such as Linux, MacOS, Windows, FreeBSD, OpenBSD, Solaris 9, NetBSD where it is also possible to compile to javascript with js_of_ocaml and also it has ocamljava that helps in compiling OCaml to Java bytecode. Whereas F3 is also quite portable as it also supports many different platforms based on its different versions of F# it can support platforms like Linux, GPU, Windows, JavaScript, MacOS, and hence the F# is said to be a cross-platform function programming language as it also supports .net.
- Debugging: In OCaml, debugging is done through interactive systems that take various inputs and checks the code, for more complex cases of debugging it provides a call tracing mechanism where the interactive systems follow the computation and another method of debugging is symbolic replay debugger which can stop the program at any time debug the code and resume the execution. Whereas in F# the debugging is done through Visual Studio or Visual studio code where it is done by stepping into line by line to check for debugging, then the entire code is debugged by running it at breakpoints and changing the execution flow when there is a pause in the debugger which indicates that debugger should start executing the next line in the code.
OCaml vs F# Comparison Table
Let us look at the comparison table of OCaml vs F#.
| OCaml | F# |
| OCaml is an industrial-strength and general-purpose programming language where it has the capability of supporting imperative, functional, and object-oriented styles. | F# is a programming language for writing simple and robust code to solve complex problems as it is a strongly-typed and functional-first programming language where it has the capability of supporting object-oriented styles and F# mature, open-source, cross-platform, functional-first programming language. |
| In the organizations when using OCamal we should note that we should be careful when using this as one mistake can costs millions which will even disturb the speed. Therefore few companies that use OCaml are Diffbot, CrowdStrike, Agora, BitMEX, Jane Street, etc. | F# helps to deal with complex computing problems using simple, robust, and maintainable code that is written in F# in many different organizations or users. Few of the companies that use F# are Trainline, Jet.com, Olo, Walmart, Improbable, goPuff, etc. |
| OCaml provides a stale syntax for writing and reading the code. It has a reasonable level where the reading of the code would not be confusing for others. | F# provides concise syntax where it is also very easy and simple to read the code which makes anyone to understand the code and also to write the code. |
| OCaml is statically typed where there is no need of writing explicit type declaration as the compiler will intimate your types. | F# is a strongly typed functional language that uses type inference which means this also does not need a declaration of the type and this is done by the compiler. |
| OCaml was initially used for developing apps that had symbolic computation, compilers, interpreters, and automatic theorem provers but now it is used to develop software in different areas. | F# is used for manipulating the objects where in this functional language it treats the objections to as another data type for functions to manipulate instead of writing code in object-oriented. |
| OCaml can also integrate with tools such as YAmL, FreeBSD, Windows, Linux, Starship, macOS, etc. | F# can integrate with tools such as canopy, MonoDevelop, .NET Core, .NET, .NET for Apache spark, Continous, etc. |
| OCaml tends to be harder when installing on windows than any other operating system and also lacks having proper tools, libraries and hence is also difficult for learning this. | As F# is a .net language and it has full support in Microsoft developer studio which tends to be more windows-centric. |
| As OCaml is an object-oriented programming language it supports features like polymorphism but it usually uses row polymorphism. | F# is also an object-oriented programming language that also supports polymorphism mainly it uses subtyping polymorphism. |
| OCaml has no such feature or ability to access the inherited object during object construction. | F# has the capability to access the base class or we can say it can access the inherited object during object construction. |
| In OCaml the instance variable is not visible outside the object. | In F#, we can see the field outside the object. |
Conclusion
In this article, we conclude that F# and OCaml are both general-purpose languages where one is function-oriented and another is object-oriented. It all depends on developers to analyze and chose the language, but most prefer to use OCaml as it is ranked 8th and F# 11th but if we go popularity wise the F# is more popular than OCaml.
