The language makes it hard to express incorrect programs by catching errors at compile time through features like enums with pattern matching, Result/Option types for error handling, move semantics by default, and type-state patterns. These features reduce the need for extensive unit testing, enable fearless refactoring, and create code that typically works once it compiles. The compiler acts as a safety net that detects bugs during development rather than in production, leading to more maintainable code and less frustration. ## Full article daily.dev links to this article rather than hosting it.
