Inheritance vs. composition in Vue

Object-oriented programming emphasizes reusing properties and defining relationships between classes, and Vue offers inheritance and composition as systems to achieve this. Inheritance in Vue allows components to inherit properties and behaviors from a parent component, creating a hierarchical structure that promotes code reuse but can result in tight coupling. This is achieved using the `extends` option, enabling child components to inherit data, computed properties, methods, and lifecycle hooks from parent components. Composition, conversely, provides greater modularity and flexibility by assembling smaller, reusable components into complex ones without relying on a strict hierarchy, allowing for easier modification and extension. It employs composables—functions returning reactive properties and methods—to encapsulate logic, which can be used across multiple components. While inheritance is beneficial for creating reusable base components and overriding behavior, composition is preferred for building modular systems with shared functionality and custom logic. The choice between inheritance and composition should consider specific design goals and requirements, with composition generally offering more flexibility due to its non-hierarchical approach.
