[Vue Principle Analysis] Virtual DOM
Vue.js is a popular JavaScript framework that uses the concept of virtual DOM to improve performance and development efficiency. Virtual DOM is one of the cores of Vue.js. It builds a lightweight DOM tree in memory instead of directly operating the real DOM, thereby reducing the number of operations on the real DOM and improving […]
