Async and Await

A promise represents a value that may be ready later. async and await let you work with promises using clean, readable code.

Marking a function async lets you await a promise inside it, pausing until the value is ready.

async function load() {
  const value = await Promise.resolve("done");
  return value;
}
load().then(result => console.log(result));

• await only works inside an async function
• An async function always returns a promise
• Use try/catch to handle errors from await
