MetaClass

A metaclass is a concept in programming that defines how classes themselves are created and behave. Think of classes as blueprints for objects; a metaclass is like a blueprint for those blueprints. It determines how new classes are constructed, what properties or methods they have, and can even modify them during creation. Essentially, metaclasses enable programmers to customize the way classes are built and function, offering a powerful way to manage and control code structure at a higher level.
