Reflection is a programming … WebPackage reflect implements run-time reflection, allowing a program to manipulate objects with arbitrary types. The typical use is to take a value with static type interface {} and extract its dynamic type information by calling TypeOf, which returns a Type. A call to ValueOf returns a Value representing the run-time data.
