Key differences between Wren and Grain
| Characteristic | Wren | Grain |
|---|---|---|
| Syntax | C-like, concise, and familiar to users of JavaScript or C-family languages. | OCaml/ReasonML-inspired, functional, and uses indentation-based blocks. |
| Paradigm | Object-oriented with some scripting features. | Functional-first, with strong emphasis on immutability and functional programming concepts. |
| Typing | Dynamically typed. | Statically typed with type inference. |
| Performance | Interpreted, generally fast for a scripting language but not as fast as compiled languages. | Compiles to WebAssembly, offering high performance suitable for web and some systems applications. |
| Libraries and frameworks | Limited standard library, few third-party libraries due to smaller ecosystem. | Growing but still limited library support, with some focus on WebAssembly and functional programming tools. |
| Community and support | Small but active community, limited resources and support. | Small, enthusiastic community, with active development and documentation efforts. |
| Learning curve | Gentle for those familiar with C-like languages; simple and approachable. | Steeper, especially for those new to functional programming or static typing. |
