hint [2/7]

## # Explanation:

You will get an array that contains sub arrays of numbers and you need to return an array with the largest number from each of the sub arrays.

hint [7/7]

## Code Solution:

function largestOfFour(arr) {
var results = [];
for (var n = 0; n < arr.length; n++) {
var largestNumber = 0;
for (var sb = 0; sb < arr[n].length; sb++) {
if (arr[n][sb] > largestNumber) {
largestNumber = arr[n][sb];
}
}

results[n] = largestNumber;
}

return results;
}

# Code Explanation:

• Create a variable to store the results as an array.
• Create an outer loop to iterate through the main array.
• Before going into the inner loop, create a variable to hold the largest number. This must be outside the inner loop.
• Create another for loop to work with the sub-arrays.
• Check if the element of the sub array is larger than the current largest number. If so, then save the number.
• After the inner loop, save the largest number in the variable for the results.
