Key differences between Gleam and OCaml
| Characteristic | Gleam | OCaml |
|---|---|---|
| Syntax | Clean, modern, and influenced by Elm and Rust; uses significant whitespace and is designed for readability and simplicity. | Traditional ML-family syntax with explicit delimiters (e.g., 'let', 'in', ';;'); can be more verbose and less familiar to newcomers. |
| Paradigm | Purely functional with strong emphasis on immutability and no side effects; designed for concurrent and fault-tolerant systems. | Multi-paradigm: primarily functional but supports imperative and object-oriented programming. |
| Typing | Statically typed with strong, sound type inference; no null or undefined values. | Statically typed with powerful type inference; supports variant types, polymorphism, and modules. |
| Performance | Compiles to Erlang BEAM or JavaScript; inherits performance characteristics of the target platform, optimized for concurrency rather than raw speed. | Compiles to native code and bytecode; generally faster for CPU-bound tasks, with efficient garbage collection and runtime. |
| Libraries and frameworks | Smaller ecosystem; can use Erlang/Elixir libraries via interop, but fewer native Gleam libraries. | Mature ecosystem with a wide range of libraries and tools, especially for systems programming, compilers, and formal methods. |
| Community and support | Growing but small community; active development and friendly support, but fewer resources. | Established community with decades of academic and industrial use; extensive documentation and support channels. |
| Learning curve | Gentle learning curve due to simple syntax and clear error messages; good for beginners in functional programming. | Moderate to steep learning curve, especially for those unfamiliar with ML syntax or advanced type system features. |
