Key differences between Wren and Gleam
| Characteristic | Wren | Gleam |
|---|---|---|
| Syntax | C-like, concise, and familiar to users of JavaScript or C-family languages. | Inspired by ML-family languages, with a clean, indentation-insensitive syntax similar to Elm or OCaml. |
| Paradigm | Object-oriented with some scripting features. | Functional, emphasizing immutability and pattern matching. |
| Typing | Dynamically typed. | Statically typed with strong type inference. |
| Performance | Interpreted, generally fast for a scripting language but not as fast as compiled languages. | Compiled to Erlang BEAM or JavaScript, offering good performance for concurrent and functional workloads. |
| Libraries and frameworks | Limited standard library, few third-party libraries due to its young ecosystem. | Can use Erlang and Elixir libraries via BEAM, but native Gleam libraries are still growing. |
| Community and support | Small but active community, limited resources and support. | Growing community, benefits from Erlang/Elixir ecosystem, more resources emerging. |
| Learning curve | Gentle for those familiar with C-like languages; simple and approachable. | Steeper for those new to functional programming, but approachable for those with ML or Elm experience. |
