# --description--
2019-12-07 17:11:14 -07:00
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.
2020-11-27 19:02:05 +01:00
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()`
