# --description--

|
|
We need a way to iterate through all the `meal` items in the `total` array and return the values that the user entered as an array.
|
||
|
|
|
||
|
|
The `map()` method allows us to do exactly that.
|
||
|
|
|
||
|
|
Delete `const meal = total[0];` and chain the `.map()` method to the end of your `Array.from()` method. Here's an example of `.map()` chained to an array: `[3, 2, 1].map()`
