Key differences between Gleam and Java
| Characteristic | Gleam | Java |
|---|---|---|
| Syntax | Clean, concise, inspired by ML-family languages; uses significant whitespace and pattern matching. | Verbose, C-style syntax with braces and semicolons; object-oriented structure. |
| Paradigm | Functional, immutable by default, strong emphasis on pure functions. | Primarily object-oriented, with some functional features since Java 8. |
| Typing | Statically typed with strong type inference and no nulls. | Statically typed, explicit type declarations, allows nulls. |
| Performance | Runs on BEAM VM (Erlang), optimized for concurrency and fault tolerance, not raw speed. | Runs on JVM, generally faster for CPU-bound tasks, mature JIT compilation. |
| Libraries and frameworks | Limited ecosystem, can use Erlang/Elixir libraries via BEAM interoperability. | Extensive ecosystem with mature libraries and frameworks for almost every domain. |
| Community and support | Small but growing community, limited resources and support. | Large, established community with abundant resources, documentation, and support. |
| Learning curve | Gentle for those familiar with functional programming; may be challenging for OOP developers. | Moderate; widely taught, lots of learning materials, familiar to many developers. |
