Key differences between TypeScript and Gleam
| Characteristic | TypeScript | Gleam |
|---|---|---|
| Syntax | C-like syntax, similar to JavaScript with added type annotations. | Clean, ML-inspired syntax, similar to Elm or OCaml. |
| Paradigm | Multi-paradigm; primarily object-oriented and functional. | Purely functional. |
| Typing | Static, structural, optionally strict, gradual typing. | Static, strong, and strict typing with type inference. |
| Performance | Runs on JavaScript engines; performance depends on JS runtime. | Compiles to Erlang or JavaScript; inherits performance characteristics of the BEAM or JS. |
| Libraries and frameworks | Extensive ecosystem; can use all JavaScript libraries and frameworks. | Smaller ecosystem; can use Erlang/Elixir libraries, but fewer native Gleam libraries. |
| Community and support | Large, active community with strong support from Microsoft and open source contributors. | Small but growing community; mostly community-driven support. |
| Learning curve | Gentle for JavaScript developers; steeper for those new to static typing. | Moderate; easier for those familiar with functional programming, but new concepts for others. |
