Here is a [cool resource about anonymous functions in JavaScript](http://helephant.com/2008/08/23/javascript-anonymous-functions/), in case you are still wondering what they are, and their role.
|
||
|
|
|
||
|
|
Now, you are tasked at putting parameters inside arrow functions.
|
||
|
|
|
||
|
|
## Hint 1:
|
||
|
|
|
||
|
|
Get rid of the `function` keyword. Put the arrow operator.
|
||
|
|
|
||
|
|
## Hint 2:
|
||
|
|
|
||
|
|
Make sure you changed the `var` to a `const`.

```
