Stop forcing users to append 'as const' to every function call just to preserve strict literal types. By simply prefixing your TypeScript generics with the 'const' keyword, you automatically lock in the strictest possible type inference. This hidden gem cleans up boilerplate while maintaining bulletproof safety.
Key insight: Adding the 'const' keyword directly before a generic type parameter automatically acts like an 'as const' assertion on the input, returning exact literal types (like 1, 2, or 3 instead of 'number').
