Final answer:
Polymorphism is a programming concept where a single interface can represent different data types, promoting flexible and reusable code while helping to reduce code bloat.
Step-by-step explanation:
The technique you are referring to is called polymorphism. In programming, polymorphism allows a single interface to represent different underlying data types. For example, in object-oriented programming, a method might take a single parameter that could be passed a string, a number, or even an object, and the method will behave appropriately depending on the type of data it is processing. This allows for more flexible and reusable code, and it helps reduce code bloat by minimizing the need for multiple similar function definitions for each data type.
