15 | ## Usage
|
---|
16 |
|
---|
17 | ```js
|
---|
18 | const pDefer = require('p-defer');
|
---|
19 |
|
---|
20 | function delay(ms) {
|
---|
21 | const deferred = pDefer();
|
---|
22 | setTimeout(deferred.resolve, ms, '🦄');
|
---|
23 | return deferred.promise;
|
---|
24 | }
|
---|
25 |
|
---|
26 | delay(100).then(console.log);
|
---|
27 | //=> '🦄'
|
---|
28 | ```
|
---|

|
---|
30 | *The above is just an example. Use [`delay`](https://github.com/sindresorhus/delay) if you need to delay a promise.*
