Key differences between Gleam and Haskell
| Characteristic | Gleam | Haskell |
|---|---|---|
| Syntax | Clean, concise, and influenced by ML-family languages; designed for readability and simplicity. | Declarative, indentation-sensitive, and heavily based on mathematical notation; can be more complex for beginners. |
| Paradigm | Functional, with a focus on immutability and purity, but pragmatic and designed for practical use. | Purely functional, emphasizing immutability, purity, and lazy evaluation. |
| Typing | Statically typed with strong, inferred types; no nulls or exceptions. | Statically typed with a powerful type system, type inference, and advanced features like type classes and monads. |
| Performance | Compiles to Erlang BEAM or JavaScript; inherits performance characteristics of those runtimes, optimized for concurrency. | Compiles to native code (via GHC); generally good performance, especially for CPU-bound tasks, but can be affected by laziness. |
| Libraries and frameworks | Smaller ecosystem, but can use Erlang and Elixir libraries; fewer frameworks available. | Mature ecosystem with a wide range of libraries and frameworks, especially for web, data, and concurrency. |
| Community and support | Growing but relatively small community; active core team and friendly support. | Large, established community with extensive resources, documentation, and academic support. |
| Learning curve | Gentle learning curve, especially for those familiar with functional programming; approachable syntax. | Steep learning curve due to advanced type system, purity, and abstract concepts. |
