Key differences between COBOL and Grain
| Characteristic | COBOL | Grain |
|---|---|---|
| Syntax | English-like, verbose, designed for readability and business logic. | Modern, concise, functional syntax inspired by OCaml and ReasonML. |
| Paradigm | Procedural, imperative, with some support for structured programming. | Functional, with strong emphasis on immutability and pure functions. |
| Typing | Static, weak typing with fixed data types and explicit declarations. | Static, strong typing with type inference and algebraic data types. |
| Performance | Optimized for batch processing and transaction-heavy workloads on mainframes. | Runs on WebAssembly, performance depends on the WASM runtime, suitable for web and modern platforms. |
| Libraries and frameworks | Limited, mostly standard libraries for business and data processing. | Growing ecosystem, but limited compared to mainstream languages; leverages WebAssembly tools. |
| Community and support | Large legacy community, strong support in enterprise and financial sectors. | Small, emerging community with active development but limited resources. |
| Learning curve | Gentle for business logic, but can be challenging due to legacy systems and verbosity. | Steep for those new to functional programming, but modern syntax aids learning. |
