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.
