## kept-promise
### Instructions
Thing in your code does not always happen as fast as you would like.
Sometimes it is important to wait for a function to finish before keep going on.
Create an asynchronous function `processInfo` in a file `kept-promise.js` . The function `processInfo` will take an asynchronous function as an input, and it will print the message `Ok!` if the return of the input function is zero or a multiple of two, `Error!` otherwise.
The following function can be used as an example of input function for `processInfo` :
```js
const getImportantInfo = _ =>
new Promise(resolve => {
setTimeout(() => resolve(Math.round(Math.random() * 10)), 1000)
})
```
> Assume that your function will always get a valid input function
### Example
The following script `main.js` can be used to test your function:
```js
import processInfo from './kept-promise.js'
const getImportantInfo = _ =>
new Promise(resolve => {
setTimeout(() => resolve(Math.round(Math.random() * 10)), 1000)
})
console.log(await processInfo(getImportantInfo))
```
The output should be the following:
```console
$ node main.js
Ok!
$ node main.js
Error!
$ node main.js
Ok!
$
```
