What is vue combination

With the development of modern Web technology and users' requirements for better user experience, the importance of JavaScript frameworks is becoming more and more significant. The three frameworks Angular, React, and Vue.js are among the most popular front-end frameworks today. While there are significant differences between these frameworks, one thing they all have in common is the idea of ​​splitting an application's UI into reusable components.

The Vue.js framework does this very well. It provides a component system that makes creating complex UI interfaces simpler, more reliable and more efficient. However, in actual projects, it is often necessary to combine multiple components to present a complete application. In this case, you need to use Vue.js combination.

So, what is Vue.js composition? Simply put, Vue.js composition is a method that can help us extract some logically related code from components, thereby making the components more concise and easier to maintain. By separating code logic from components, we can better reuse that logic and test it more easily.

Vue.js composition is implemented using the Composition API of Vue.js 3.0. It provides a new way to organize and manage data, computed properties and methods in Vue.js components. In Vue.js 2.x version, we use Mixins to achieve code reuse. In Vue.js 3.0, Mixins were deprecated and replaced by the Composition API, which provides better composability and code reusability.

The core idea of ​​Vue.js composition is to encapsulate data-related code in a custom JavaScript function and return it to the component. This function can use some of the new reactive APIs introduced in Vue.js 3.0, such as reactive, computed and watchEffect.

By using Vue.js composition, we can break down complex data logic into smaller pieces of logic and assemble them into reusable functions and components. In doing so, you not only improve the readability and maintainability of your code, but also make your components cleaner and streamlined.

Overall, Vue.js composition is a very powerful tool that can help us better organize and manage code and improve the performance and reusability of Vue.js applications. Vue.js composition is undoubtedly an indispensable technology in today's environment where large and complex applications need to be built.
