Key differences between Elm and Gleam
| Characteristic | Elm | Gleam |
|---|---|---|
| Syntax | Clean, Haskell-inspired syntax focused on simplicity and readability for front-end development. | OCaml/ReasonML-inspired syntax, concise and designed for clarity, targeting the BEAM ecosystem. |
| Paradigm | Purely functional, enforces immutability and no side effects, designed for building reliable web apps. | Functional, with strong emphasis on immutability and pattern matching, designed for concurrent and fault-tolerant systems. |
| Typing | Static, strong type system with type inference, no null or runtime exceptions. | Static, strong type system with type inference, designed to catch errors at compile time. |
| Performance | Compiles to highly optimized JavaScript, fast for front-end applications. | Compiles to efficient Erlang or JavaScript code, leverages BEAM's concurrency and reliability. |
| Libraries and frameworks | Curated package ecosystem, limited but high-quality libraries focused on front-end development. | Growing ecosystem, can interoperate with Erlang and Elixir libraries, more options for back-end and distributed systems. |
| Community and support | Active but smaller community, strong focus on stability and beginner-friendliness. | Smaller and newer community, but growing interest due to BEAM compatibility. |
| Learning curve | Gentle learning curve for those new to functional programming, excellent documentation. | Moderate learning curve, especially for those familiar with BEAM or functional languages, documentation improving. |
