Key differences between Java and Grain
| Characteristic | Java | Grain |
|---|---|---|
| Syntax | C-style, verbose, uses curly braces and semicolons, object-oriented structure. | OCaml/ReasonML-inspired, concise, functional, uses indentation and type inference. |
| Paradigm | Primarily object-oriented, supports imperative and some functional features. | Functional-first, supports immutability, pattern matching, and algebraic data types. |
| Typing | Statically typed, explicit type declarations, strong type system. | Statically typed, type inference, strong and expressive type system. |
| Performance | High performance via JVM and JIT compilation, suitable for large-scale applications. | Compiles to WebAssembly, optimized for web performance, not as mature as JVM. |
| Libraries and frameworks | Extensive ecosystem, mature libraries and frameworks for various domains. | Smaller ecosystem, limited libraries, focused on WebAssembly and functional programming. |
| Community and support | Large, global community, extensive documentation, strong industry support. | Small, growing community, limited resources, mostly open-source contributors. |
| Learning curve | Moderate, well-documented, familiar to many due to widespread use. | Steeper for those new to functional programming, less documentation and resources. |
