Vue Composition API
The Vue Composition API is a set of APIs introduced in Vue 3 that allows developers to organize component logic using functions instead of options-based syntax. It provides reactive state management, lifecycle hooks, and computed properties through functions like ref, reactive, and computed, enabling more flexible and reusable code composition. This API is particularly useful for building complex components and managing state in large-scale Vue applications.
Developers should learn the Vue Composition API when working with Vue 3 to handle complex component logic, improve code reusability through composable functions, and manage state more effectively in large applications. It is essential for building scalable Vue projects, integrating with TypeScript for better type safety, and creating maintainable codebases where logic can be shared across components.
