Key differences between Java and Gleam
| Characteristic | Java | Gleam |
|---|---|---|
| Syntax | C-style, verbose, uses curly braces and semicolons | Concise, inspired by ML-family languages, uses indentation and pattern matching |
| Paradigm | Object-oriented, imperative, some functional features | Functional, immutable by default, no object-oriented features |
| Typing | Statically typed, nominal typing, explicit type declarations | Statically typed, strong type inference, algebraic data types |
| Performance | High performance via JVM JIT compilation, mature garbage collection | Runs on BEAM (Erlang VM), optimized for concurrency and fault-tolerance, not focused on raw speed |
| Libraries and frameworks | Extensive standard library, vast ecosystem of libraries and frameworks | Smaller ecosystem, can use Erlang and Elixir libraries, growing set of native libraries |
| Community and support | Large, mature, global community with extensive support resources | Small but active and growing community, limited support resources |
| Learning curve | Moderate, well-documented, many learning resources available | Gentle for those familiar with functional programming, steeper for newcomers, fewer resources |
