Key differences between Erlang and Gleam
| Characteristic | Erlang | Gleam |
|---|---|---|
| Syntax | Prolog-inspired, uses commas and periods to separate expressions, less familiar to most programmers. | Rust/Elm-like, more modern and familiar syntax, uses indentation and braces, easier to read for many developers. |
| Paradigm | Functional, concurrent, actor model, designed for distributed systems. | Functional, immutable data, compiles to Erlang VM, leverages actor model via BEAM. |
| Typing | Dynamically typed, no static type checking. | Statically typed, strong type inference, catches errors at compile time. |
| Performance | Highly performant for concurrent and distributed systems, mature VM (BEAM). | Similar performance to Erlang since it compiles to BEAM, but may have minor overhead due to abstractions. |
| Libraries and frameworks | Rich ecosystem, mature libraries and frameworks (e.g., OTP, Cowboy, RabbitMQ). | Can use Erlang/Elixir libraries via interop, but native Gleam libraries and frameworks are still growing. |
| Community and support | Large, established community, extensive documentation and support. | Smaller, newer community, growing support and documentation. |
| Learning curve | Steep, due to unique syntax and concurrency model. | Gentler, especially for those familiar with modern statically typed languages. |
