Key differences between Fsharp and Gleam
| Characteristic | Fsharp | 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. |
