Key differences between Gleam and Wren
| Characteristic | Gleam | Wren |
|---|---|---|
| Syntax | Inspired by ML-family languages (like OCaml and Elm); uses significant whitespace and a clean, functional style. | C-style syntax; familiar to users of JavaScript, C, or Java; uses braces and semicolons. |
| Paradigm | Purely functional; emphasizes immutability and pattern matching. | Object-oriented with some scripting features; supports classes and methods. |
| Typing | Statically typed with strong type inference; catches errors at compile time. | Dynamically typed; types are checked at runtime. |
| Performance | Compiles to Erlang BEAM or JavaScript; inherits performance characteristics of the target platform (Erlang VM is highly concurrent). | Interpreted language; generally fast for a scripting language but not as performant as compiled languages. |
| Libraries and frameworks | Limited ecosystem; can use Erlang/Elixir libraries via interop, but native Gleam libraries are still growing. | Minimal standard library; few third-party libraries; designed to be embedded in applications rather than for standalone use. |
| Community and support | Small but active and growing community; good official documentation; support mainly via GitHub and Discord. | Small community; limited resources and support; mostly maintained by a few core contributors. |
| Learning curve | Moderate; functional programming concepts and static typing may be new to some, but syntax is approachable. | Low; familiar syntax for those with experience in C-like languages; easy to pick up for scripting tasks. |
