// 使用Webpack等工具进行代码分割
import('./module.js').then(module => {
    // Use module
});

// 启用Gzip压缩
const compression = require('compression');
app.use(compression());

// 使用CDN加速静态资源加载
<link rel="stylesheet" href="https://cdn.example.com/styles.css">

// 异步加载JavaScript
<script src="script.js" async></script>
<script src="script.js" defer></script>

// 使用Web Workers处理复杂计算
const worker = new Worker('worker.js');
worker.postMessage({ data: 'some data' });
worker.onmessage = function(event) {
    console.log('Received message from worker', event.data);
};
