Key differences between Pascal and Gleam
| Characteristic | Pascal | Gleam |
|---|---|---|
| Syntax | Verbose, uses begin/end blocks, influenced by ALGOL, designed for readability and teaching. | Concise, modern, indentation-based, inspired by ML-family languages, designed for clarity and safety. |
| Paradigm | Imperative and procedural, with some support for structured and object-oriented programming (in later versions). | Functional, strongly emphasizes immutability and pure functions, designed for concurrent and fault-tolerant systems. |
| Typing | Statically typed, strong type checking, explicit type declarations required. | Statically typed, strong and inferred typing, with a focus on type safety and pattern matching. |
| Performance | Compiled to native code, generally fast for its era, but lacks modern optimizations. | Compiles to Erlang BEAM bytecode or JavaScript, performance depends on target platform, optimized for concurrency rather than raw speed. |
| Libraries and frameworks | Limited modern libraries, some legacy frameworks, mostly for education and legacy systems. | Growing ecosystem, can use Erlang and Elixir libraries, but native Gleam libraries are still limited. |
| Community and support | Small, mostly legacy and educational, limited active development and support. | Small but active and growing, strong engagement from functional programming enthusiasts, responsive maintainers. |
| Learning curve | Gentle, designed for teaching programming fundamentals, easy for beginners. | Moderate, functional paradigm may be challenging for newcomers, but syntax and tooling aim to ease learning. |
