JavaScript - find min value in array with Array reduce method

In this article, we would like to show you how to find the minimum value in an array working with JavaScript.

1. Array reduce method example (ES6+)

// ONLINE-RUNNER:browser;

const array = [3, 1, 2];

const result = array.reduce((a, b) => Math.min(a, b));

console.log(result);  // 1

With nested properties:

// ONLINE-RUNNER:browser;

const array = [{value: 1}, {value: 2}, {value: 3}];
const result = array.reduce((r, b) => Math.min(r, b.value), Number.POSITIVE_INFINITY);

console.log(result);

2. ES5 example

In ECMAScript 2009 we need to use classic function notation.

// ONLINE-RUNNER:browser;

var array = [1, 2, 3];

var result = array.reduce(function(a, b) {
    return Math.max(a, b);
});

console.log(result);
