What is prototype-based inheritance and how does it differ from classical class-based inheritance?

Accepted Answer

Prototype-based inheritance in JavaScript allows objects to inherit directly from other objects via the prototype chain at runtime. This differs from classical inheritance, where class blueprints define instance structure at class definition time. JavaScript's class syntax is just syntactic sugar over prototype inheritance.
