Key differences between Nim and Gleam
| Characteristic | Nim | Gleam |
|---|---|---|
| Syntax | Python-like, indentation-based, readable and expressive with optional curly braces. | Inspired by ML-family languages, statically indented, concise, and designed for clarity. |
| Paradigm | Multi-paradigm: supports procedural, object-oriented, and functional programming. | Functional, strongly influenced by Erlang/Elixir, emphasizes immutability and pattern matching. |
| Typing | Statically typed with type inference, supports generics and metaprogramming. | Statically typed with strong type inference, no runtime type errors, no nulls. |
| Performance | Compiles to C, C++, or JavaScript; produces fast native binaries with performance close to C. | Compiles to Erlang BEAM or JavaScript; performance similar to Erlang, optimized for concurrency rather than raw speed. |
| Libraries and frameworks | Growing standard library, access to C libraries, some frameworks for web and GUI, but ecosystem is smaller than mainstream languages. | Smaller ecosystem, can use Erlang/Elixir libraries, but native Gleam libraries and frameworks are limited. |
| Community and support | Active but relatively small community, good documentation, active development. | Very small but enthusiastic community, documentation is improving, project is young and evolving. |
| Learning curve | Gentle for those familiar with Python or Pascal, but advanced features and metaprogramming can be complex. | Easy to pick up for those with functional programming background, but Erlang/BEAM concepts may be new to some. |
