Invokes the provided function after `ms` milliseconds.
|
|
|
|
- Use `setTimeout()` to delay execution of `fn`.
|
|
- Use the spread (`...`) operator to supply the function with an arbitrary number of arguments.
|
|
|
|
```js
|
|
const delay = (fn, ms, ...args) => setTimeout(fn, ms, ...args);
|
|
```
|
|
|
|
```js
|
|
delay(
|
|
function(text) {
|
|
console.log(text);
|
|
},
|
|
1000,
|
|
'later'
|
|
); // Logs 'later' after one second.
|
|
```
