Key differences between F# and Gleam
| Characteristic | F# | Gleam |
|---|---|---|
| Syntax | OCaml-inspired, concise, indentation-sensitive, integrates with .NET syntax. | Erlang/ML-inspired, very minimal, whitespace-insensitive, designed for clarity and simplicity. |
| Paradigm | Multi-paradigm: functional-first with strong support for OOP and imperative styles. | Purely functional, no OOP, focuses on immutability and simplicity. |
| Typing | Statically typed, type inference, .NET type system, supports generics and type providers. | Statically typed, strong type inference, no subtyping, simple and strict type system. |
| Performance | Runs on .NET CLR, performance comparable to C# and other .NET languages. | Compiles to Erlang BEAM or JavaScript, inherits BEAM's concurrency and reliability, not focused on raw speed. |
| Libraries and frameworks | Access to vast .NET ecosystem, many libraries and frameworks for web, data, and more. | Smaller ecosystem, can use Erlang/Elixir libraries via interop, but fewer native Gleam libraries. |
| Community and support | Established, active community, Microsoft support, good documentation and resources. | Growing but small community, mostly open-source driven, limited resources and documentation. |
| Learning curve | Moderate, easier for those familiar with .NET or functional programming, some unique features. | Gentle, designed for approachability, simple syntax and semantics, but less learning material. |
Frequently Asked Questions
How do I convert F# to Gleam?
Paste your F# code into the input box, confirm the languages are set to F# and Gleam, and click Convert. CodeConvert AI analyzes your F# code and generates equivalent Gleam code in seconds, preserving the original logic and structure.
What are the main differences between F# and Gleam?
F# and Gleam differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each F# construct to its closest Gleam equivalent. See the comparison table below for the key differences between F# and Gleam.
Is the converted Gleam code accurate?
The AI produces high-quality Gleam code that preserves the behavior of your original F# code and follows Gleam conventions. It handles common patterns, data structures, and idioms for both F# and Gleam. For large or performance-critical code, review and test the Gleam output before using it in production.
Can I convert an entire F# project to Gleam?
You can convert F# files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from F# to Gleam. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Gleam back to F#?
