This free online converter lets you convert code from VB6 to Gleam in a click of a button. To use this converter, take the following steps -
| Characteristic | VB6 | Gleam |
|---|---|---|
| Syntax | English-like, verbose, uses BEGIN/END blocks, familiar to BASIC users. | Concise, modern, inspired by ML-family languages, uses indentation and pattern matching. |
| Paradigm | Primarily imperative and event-driven, supports object-based programming. | Functional, strongly emphasizes immutability and pure functions. |
| Typing | Dynamically typed with optional static typing (Variant by default). | Statically and strongly typed with type inference. |
| Performance | Interpreted or compiled to native code, generally slower and less optimized. | Compiles to Erlang BEAM bytecode, benefits from Erlang VM's concurrency and performance. |
| Libraries and frameworks | Rich set of built-in GUI and database libraries, but outdated and limited to Windows. | Growing ecosystem, leverages Erlang/Elixir libraries, but fewer native libraries. |
| Community and support | Large legacy community, but official support ended; mostly maintained by enthusiasts. | Small but active and growing community, modern support channels. |
| Learning curve | Gentle for beginners, especially those familiar with BASIC or Windows development. | Steeper due to functional paradigm and modern type system, easier for those with functional programming experience. |
