Key differences between JavaScript and Grain
| Characteristic | JavaScript | Grain |
|---|---|---|
| Syntax | C-like, flexible, dynamic, and widely known syntax. | OCaml-inspired, functional, statically-typed syntax. |
| Paradigm | Multi-paradigm: supports functional, imperative, and object-oriented programming. | Primarily functional, with strong emphasis on immutability and pure functions. |
| Typing | Dynamically typed, with optional static typing via TypeScript. | Statically typed with type inference, similar to ML-family languages. |
| Performance | Highly optimized engines (e.g., V8), fast for most web use cases. | Compiles to WebAssembly, offering near-native performance for compute-heavy tasks. |
| Libraries and frameworks | Extensive ecosystem with thousands of libraries and frameworks (React, Angular, etc.). | Limited ecosystem; fewer libraries and frameworks available. |
| Community and support | Large, active global community with abundant resources and support. | Small, emerging community with limited resources and support. |
| Learning curve | Gentle learning curve, especially for beginners; widely taught. | Steeper learning curve due to functional paradigm and less documentation. |
