Parameters Utility Type
Last updated
What is Parameters Utility Type?
The Parameters utility type in TypeScript extracts the parameter types of a function type into a tuple. This allows you to programmatically determine the expected arguments of a function and use them in other type definitions, providing type safety and flexibility when working with function signatures. The result is a tuple type where each element represents the type of a parameter in the function.
