- Roc is a single-paradigm functional language with a focus on simplicity and performance.
- Roc uses opportunistic mutation to optimize performance while maintaining semantic immutability.
- Semantic immutability in Roc eliminates data races and reference cycles, enhancing reliability and performance.
- Roc disallows reassignment and shadowing, making code easier to read and rearrange without regressions.
- Roc employs managed effects (Tasks) instead of side effects, ensuring all functions are pure.
- Pure functions in Roc enable compiler optimizations like loop fusion, compile-time evaluation, and hoisting.
- Roc's design choices support easier debugging, testing, and optimization, though some algorithms may be harder to express.
