I have a multidimensional array with names and corresponding integer values. I want to compare the integer values within each nested array to find and return the one with the highest value.
var nums = [
['alice', 'exam', 60],
['dave', 'quiz', 85]
];
What is the best way to iterate through the arrays in the "nums" array and identify the array with the greatest integer value?
An alternative method to achieve this is by using the reduce function in JavaScript. Here's an example:
var data = [
['alice', 'test', 80],
['bob', 'quiz', 92],
['carol', 'exam', 75],
['dave', 'homework', 88]
];
var highestScore = data.reduce((prev, current) => prev[2] > current[2] ? prev : current);
console.log(highestScore);

Keep in mind that when using reduce() without an initial value, the first item becomes a and the second item becomes b in the first iteration.
let maxNumber = totals.reduce((prev, cur) => prev[2] > cur[2] ? prev : cur, [0,0,0]);
Let's use the reduce method to find the highest total in the array:
var result = totals.reduce((p, c) => {
return p[2] > c[2] ? p : c;
});
console.log(result);
