Key differences between Grain and Gleam
| Characteristic | Grain | Gleam |
|---|---|---|
| Syntax | OCaml-inspired, functional-first syntax with some JavaScript-like elements. | Clean, ML-style syntax, similar to Elm or ReasonML, designed for clarity and simplicity. |
| Paradigm | Functional-first, supports imperative constructs, strong emphasis on immutability. | Purely functional, immutable by default, designed for reliability and maintainability. |
| Typing | Statically typed with type inference, inspired by ML-family languages. | Statically typed with strong type inference, similar to Elm and Haskell. |
| Performance | Compiles to WebAssembly, aiming for high performance in browser and server environments. | Compiles to Erlang BEAM and JavaScript, performance is good for concurrent and distributed systems but not as fast as native or WebAssembly. |
| Libraries and frameworks | Smaller ecosystem, growing set of core libraries, limited third-party frameworks. | Leverages Erlang/Elixir ecosystem, can use many BEAM libraries, but native Gleam libraries are still developing. |
| Community and support | Small but active community, official Discord and documentation, limited third-party resources. | Small but enthusiastic community, good documentation, active Discord, benefits from Erlang/Elixir community. |
| Learning curve | Moderate; easier for those familiar with functional languages, some unique concepts for newcomers. | Gentle; designed for approachability, especially for those new to functional programming. |
