## Description
Now we need to provide a function to `map()` that will be performed on each item of the array.
This function will take the original item as an argument, in our case we'll call it `meal`. Inside the `.map()` parentheses, insert an empty function that takes `meal` as a parameter, like:
```js
function(meal){}
```
Enter in the above function as an argument in between the parentheses of the `.map()` function.
