一句话:针对 React 应用中的多余重渲染问题,提出修复或缓解技术。
React 是流行的 UI 框架,界面以组件树组织,组件由返回 JSX 的函数定义;JSX 混合 XML 标签、可执行 JavaScript 与子组件引用。React 通过维护网页 DOM 的内存表示,并在状态变化时自动计算需应用到 DOM 的最小变更,从而支持增量重渲染。该机制可能产生多余重渲染,带来不必要的计算开销。论文标题表明其目标是修复或缓解此类多余重渲染,但所给摘要仅介绍背景,未说明具体方法、实现与实验评估,因此无法从摘要判断关键结果。
React is an extremely popular framework for constructing user interfaces (UIs). A React UI is organized as a tree of components, each of which is defined by a function that returns a literal written in JSX, a syntactic extension of JavaScript consisting of a combination of XML tags, executable JavaScript code, and references to sub-components. React supports incremental re-rendering by maintaining an in-memory representation of a web page’s Document Object Model (DOM) and automatically calculating a set of minimal changes that must be applied to the DOM when state changes occur.
