generics

Generics are a feature in programming that allows developers to write flexible and reusable code. Instead of creating separate functions or classes for different data types (like integers, strings, or custom objects), generics enable the same code to work with any type. This is achieved by defining a placeholder for the data type, which is specified when the code is used. For example, a generic list can store any type of item, ensuring type safety and reducing duplicate code, making programs more efficient and easier to maintain.
