Vue.js (vue for short) is a popular JavaScript framework for building user interfaces. It was created by You Yuxi in 2014 and has become one of the most popular frameworks in web development. Vue.js provides a responsive and component-based architecture that makes it easy to develop interactive applications and seamlessly integrates with other libraries and frameworks.
Due to the popularity of Vue.js, many of its APIs and features have become more and more popular. Vue.set is one of them. Vue.set is a core API of Vue.js that is used to add new properties to reactive objects and ensure that views are updated responsively. The Vue.set method is very convenient, especially when using the v-for instruction, but where does the vue of Vue.set come from?
To understand the vue of Vue.set, we need to review the origin and design philosophy of Vue.js. In 2013 and 2014, You Yuxi began to develop the prototype of Vue.js. Prior to this, he has made several contributions to other frameworks and libraries, including Angular.js and Meteor. What these frameworks have in common is support for two-way data binding. That is, when the data changes, the view changes accordingly.
However, the disadvantage of this implementation is that it can make the entire application slow down, especially for large-scale applications or applications with large amounts of data. This is because every time the data changes, the entire data structure needs to be traversed to determine which parts of the view need to be updated. When building large-scale web applications, this will greatly impact the application's performance and user experience.
In order to solve this problem, You Yuxi created Vue.js. Vue.js adopts a more elegant solution: responsiveness. The reactive principle of Vue.js is that when data changes, only the affected parts are updated, not the entire application. It does this by listening for changes in data objects and having greater efficiency in views.
Vue.js implements reactivity by wrapping data properties with getters and setters. In addition, it also provides two APIs, Vue.set and Vue.delete, for adding and deleting responsive properties. These APIs are very powerful, especially when developing applications with complex state. Use Vue.set and Vue.delete to ensure that added and deleted properties are responsive and update the view correctly.
It is worth noting that Vue.js is designed to optimize performance while maintaining flexibility. It provides a lightweight solution to flexibly integrate Vue.js with other libraries and frameworks. This is another advantage of Vue.js that makes it one of the most popular frameworks for web development.
In short, the vue of Vue.set comes from the origin and design concept of the Vue.js framework. Vue.js adopts a reactive implementation that improves application performance by wrapping data properties with getters and setters. Moreover, APIs such as Vue.set and Vue.delete are also part of the Vue.js design. They provide a convenient way to add or remove properties to responsive objects and ensure that the view responds to changes correctly. Vue.js is easy to learn and suitable for various application scenarios. It has become one of the preferred frameworks for many web developers.
