JavaScript Async_await Guide
Async/await makes async code read like synchronous code. It is built on Promises and is the modern standard for JavaScript asynchronous programming. The guide walks through Async Functions. `async function fn() { return await promise }`. Always returns a Promise. `await` pauses until Promise settles. Error handling: `try { const r = await fn() } catch(e) { }`. Parallel: `const [a,b] = await Promise.all([fn1(),fn2()])`. Sequential: `const a = await fn1(); const b = await fn2(a)`. The guide is organized into 1 sections that build on each other, each pairing a prose explanation with runnable code. Related guides: Arrays, Strings, Numbers, Math, Date. This is one of 145 JavaScript guides on JS Reference — see the full list on the guides page. Practice what you learn in the JavaScript playground, and look up any unfamiliar term in the JavaScript glossary.
