When working with numeric arrays in JavaScript, you might find yourself in need of finding the minimum or maximum value. Luckily, JavaScript's Math built-in object has got you covered. You can simply use Math.min() or Math.max() combined with the spread operator (...), as both functions accept any number of arguments.

const nums = [2, 4, 6, 8, 1, 3, 5, 7];

Math.max(...nums); // 8
Math.min(...nums); // 1

For more complex cases, such as finding the min/max value in an array of objects, you might have to resort to Array.prototype.map() or Array.prototype.reduce(). On the other hand, our minBy or maxBy snippets might be all you need.
