TypeScript's type system has evolved significantly in recent years, especially with the introduction of generics and conditional types, which have further enhanced type safety. So, when a function needs to handle different data types with the same logic, how can we define generics in the most efficient way? Additionally, how can we maximize type safety while maintaining code readability by combining type inference with default generic parameters? I'd love to hear your experiences and suggestions on this!
How can we maximize type safety in TypeScript using generics?

Thanks for the question! The best approach is to link the generics with constraints (`extends`) and set default values for the parameters, like `function merge<T extends object, U extends object = {}>(a: T, b: U): T & U` to leverage type inference while keeping the code clear. Have you tried combining conditional types with `infer` to reduce the number of overloads and improve maintainability?
