## Issue

Given the array below, how I can return the element whose first index contains the highest number:

```
let ar = [[1,24], [2, 6]]
```

I’ve tried many proposed solutions, but they return the number itself, while it should be, in the case above `[2,6]`

One of the solutions I’ve tried is, but it returns `24, 6`

:

```
var maxRow = arr.map(function(row){ return Math.max.apply(Math, row); });
```

## Solution

To do what you require you can use `reduce()`

to compare the values of the first item in each child array and return the one with the highest value:

```
let ar = [[1,24], [2, 6]]
let result = ar.reduce((acc, cur) => acc[0] < cur[0] ? cur : acc);
console.log(result);
```
