Type Safety
Type safety is a programming language feature that ensures operations are performed on data of appropriate types, preventing type errors at compile-time or runtime. It involves static or dynamic type checking to enforce type constraints, such as disallowing operations like adding a string to an integer. This concept is fundamental in software development for reducing bugs and improving code reliability.
Developers should prioritize type safety when building large-scale, maintainable applications where catching errors early is critical, such as in enterprise software, financial systems, or safety-critical domains. It enhances code quality by providing better tooling support (e.g., autocompletion, refactoring) and documentation through type annotations, leading to fewer runtime crashes and easier debugging.
