The article explores the 'never' type in TypeScript, illustrating its significance and applications in ensuring safety and correctness in type-level programming. It delves into how 'never' functions as a bottom type, represents the empty set, and plays integral roles in filtering union types and performing exhaustiveness checks at compile time. By utilizing conditional types, developers can effectively manage unions and enforce type constraints, thus avoiding potential errors. Practical examples demonstrate its utility in scenarios like forbidding properties and ensuring all enum values are considered, enhancing TypeScript's type system's robustness.
The 'never' type in TypeScript represents values that never occur and has applications in filtering types, enforcing exhaustiveness checks, and forbidding properties.
