Delays the execution of an asynchronous function.
|
|
|
|
- Delay executing part of an `async` function, by putting it to sleep, returning a `new Promise()`.
|
|
|
|
```js
|
|
const sleep = ms => new Promise(resolve => setTimeout(resolve, ms));
|
|
```
|
|
|
|
```js
|
|
async function sleepyWork() {
|
|
console.log("I'm going to sleep for 1 second.");
|
|
await sleep(1000);
|
|
console.log('I woke up after 1 second.');
|
|
}
|
|
```
