Key differences between Elm and Grain
| Characteristic | Elm | Grain |
|---|---|---|
| Syntax | Haskell-like, functional, uses significant whitespace, concise and readable. | OCaml-inspired, functional, uses braces and semicolons, more familiar to those with C-style backgrounds. |
| Paradigm | Purely functional, immutable data, no side effects outside of managed effects. | Functional-first, supports immutability, but allows some imperative constructs. |
| Typing | Statically typed, strong type inference, no null or undefined, enforced immutability. | Statically typed, strong type inference, based on Hindley-Milner, supports algebraic data types. |
| Performance | Compiles to highly optimized JavaScript, fast for web UIs. | Compiles to WebAssembly, aims for high performance and low-level control. |
| Libraries and frameworks | Rich ecosystem for web development, especially for building SPAs, limited interop with JavaScript. | Smaller ecosystem, general-purpose, can interoperate with JavaScript and WebAssembly modules. |
| Community and support | Established, active community, good documentation, slower recent development. | Growing but smaller community, active development, documentation improving. |
| Learning curve | Gentle for beginners, excellent error messages, functional concepts may be new to some. | Moderate, especially for those new to functional programming or OCaml-like syntax. |
