Language comparison
Key differences between VB6 and Grain
| Characteristic | VB6 | Grain |
|---|---|---|
| Syntax | English-like, verbose, uses 'Dim', 'Sub', 'End', and other BASIC-style keywords. | Functional, concise, uses pattern matching, type annotations, and OCaml/Elm-like syntax. |
| Paradigm | Primarily event-driven and object-based, with some support for procedural programming. | Purely functional, emphasizing immutability and strong type safety. |
| Typing | Weakly and optionally typed, with implicit conversions and late binding. | Statically and strongly typed, with type inference and no implicit conversions. |
| Performance | Interpreted or compiled to native code, generally fast for desktop apps but limited by legacy runtime. | Compiles to WebAssembly, offering high performance for web applications. |
| Libraries and frameworks | Rich set of built-in controls and libraries for Windows GUI and database access. | Limited but growing ecosystem, focused on web and functional programming libraries. |
| Community and support | Large legacy community, but official support ended; mostly maintained by enthusiasts. | Small but active and modern community, with ongoing development and support. |
| Learning curve | Gentle for beginners, especially those new to programming or Windows development. | Steeper, especially for those unfamiliar with functional programming concepts. |
