Creates a promise that resolves after a given amount of time to the provided value.
|
|
|
|
- Use the `Promise` constructor to create a new promise.
|
|
- Use `setTimeout()` to call the promise's `resolve` function with the passed `value` after the specified `delay`.
|
|
|
|
```js
|
|
const resolveAfter = (value, delay) =>
|
|
new Promise(resolve => {
|
|
setTimeout(() => resolve(value, delay));
|
|
});
|
|
```
|
|
|
|
```js
|
|
resolveAfter('Hello', 1000);
|
|
// Returns a promise that resolves to 'Hello' after 1s
|
|
```
