如何从Array / Angular中的元素中获取最低值

const arr = [5, 2, 8, 1, 9];
const min = Math.min(...arr);
console.log(min); // 输出1

const arr = [5, 2, 8, 1, 9];
const min = arr.reduce((a, b) => Math.min(a, b));
console.log(min); // 输出1

const arr = [5, 2, 8, 1, 9];
arr.sort((a, b) => a - b);
const min = arr[0];
console.log(min); // 输出1

const _ = require('lodash');
const arr = [5, 2, 8, 1, 9];
const min = _.min(arr);
console.log(min); // 输出1
