| Syntax | Inspired by OCaml and ReasonML, uses functional syntax with pattern matching and type inference. | C-style syntax, verbose, uses curly braces and semicolons, object-oriented structure. |
| Paradigm | Primarily functional, supports immutability and first-class functions. | Primarily object-oriented, with some functional features since Java 8. |
| Typing | Statically typed with strong type inference. | Statically typed, explicit type declarations required. |
| Performance | Compiles to WebAssembly, optimized for web performance but generally less mature than JVM. | Runs on the JVM, highly optimized for server and desktop performance. |
| Libraries and frameworks | Limited ecosystem, fewer libraries and frameworks due to its youth. | Extensive ecosystem with mature libraries and frameworks for almost every use case. |
| Community and support | Small, growing community with limited support resources. | Large, established community with abundant support and resources. |
| Learning curve | Steeper for those unfamiliar with functional programming concepts. | Moderate, especially for those with experience in C-style languages. |
