Key differences between Grain and JavaScript
| Characteristic | Grain | JavaScript |
|---|---|---|
| Syntax | Syntax is inspired by OCaml and ReasonML, featuring significant whitespace, pattern matching, and functional constructs. | C-style syntax with curly braces, semicolons, and flexible structure; familiar to most web developers. |
| Paradigm | Primarily functional, with strong emphasis on immutability and pure functions. | Multi-paradigm: supports functional, object-oriented, and imperative programming. |
| Typing | Statically typed with type inference; types are checked at compile time. | Dynamically typed; types are checked at runtime. |
| Performance | Compiles to WebAssembly, offering near-native performance in supported environments. | Interpreted or JIT-compiled; performance is generally good but can be slower than WebAssembly for compute-heavy tasks. |
| Libraries and frameworks | Limited ecosystem; fewer libraries and frameworks available due to its youth and niche use. | Extensive ecosystem with thousands of libraries and frameworks for all kinds of applications. |
| Community and support | Small and growing community; limited resources and support. | Large, mature, and active community with abundant resources, tutorials, and support. |
| Learning curve | Steeper learning curve, especially for those unfamiliar with functional programming or OCaml-like syntax. | Gentle learning curve for beginners; widely taught and used as an entry point to programming. |
