<link> 元素的 rel 属性的 prerender 关键字向浏览器暗示用户下次导航可能需要目标资源，因此浏览器可以通过抢先获取和处理资源来改善用户体验 - 例如， 通过获取其子资源或在屏幕外的背景中执行一些渲染。
¥The prerender keyword for the rel attribute of the <link> element is a hint to browsers that the user might need the target resource for the next navigation, and therefore the browser can likely improve the user experience by preemptively fetching and processing the resource — for example, by fetching its subresources or performing some rendering in the background offscreen.
此功能已被 推测规则 API 取代。
¥This feature is superceded by the Speculation Rules API.
