<h2>未来趋势</h2>
<div class="trend-demo">
<h3>Web技术发展方向</h3>
<div class="code-block">
<pre>
// Web技术未来趋势
// 1. 性能优化趋势
// - 更快的加载速度
// - 更低的资源消耗
// - 更好的用户体验
// 新性能API示例
async function useNewPerformanceAPIs() {
// Performance Timeline API
const entries = performance.getEntriesByType('navigation');
console.log('页面加载时间:', entries[0].loadEventEnd);
// Long Tasks API
const observer = new PerformanceObserver((list) => {
for (const entry of list.getEntries()) {
console.log('长任务:', entry.duration);
}
});
observer.observe({ entryTypes: ['longtask'] });
// Layout Instability API
const layoutShiftObserver = new PerformanceObserver((list) => {
for (const entry of list.getEntries()) {
console.log('布局偏移:', entry.value);
}
});
layoutShiftObserver.observe({ entryTypes: ['layout-shift'] });
}
// 2. 交互体验趋势
// - 更自然的交互方式
// - 更沉浸的用户体验
// - 更智能的界面
// WebXR示例
async function useWebXR() {
// 检查支持
if ('xr' in navigator) {
const supported = await navigator.xr.isSessionSupported('immersive-vr');
if (supported) {
// 创建VR会话
const session = await navigator.xr.requestSession('immersive-vr');
// 获取渲染层
