**Tell us what’s happening:**

I want to know how to express the same code using Arrow Functions. I think that I should start learning this kind of coding because is more concise than the traditional, and I know that companies are looking for people who know how to write concise code.

**Your code so far**

function largestOfFour(arr) {

// You can do this!

‘create an Array’

let newArr=[];

‘search in each indexed array’

for (let i = 0; i<arr.length;i++){

let value = Math.max(…arr[i]);

newArr.push(value);

}

return newArr;

}

largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);

```
