try { await run(); } catch(err) { } 但在这个例子中这是不可能的,因为我们不能在主线程中使用await- 它只能在异步函数中使用(因为没有人想阻塞主线程)。要测试处理是否以“同步样式”工作,我们可以从另一个异步函数调用run函数或使用 IIFE(立即调用函数表达式:MDN): (async function() { try { await ...

So, to run all these APIs in parallel, we can use Promise.all() like so.async function fetchUserResources() { const [posts, photos, todos] = await Promise.all([ fetch('https://jsonplaceholder.typicode.com/posts/1'), fetch('https://jsonplaceholder.typicode.com/photos/1'), fetch('...
