var numbers = [-5, 10, -3, 15, 7];

var max = Math.max.apply(null, numbers);

var min = Math.min.apply(null, numbers);

console.log('Max value: ' + max); // 输出: Max value: 15

console.log('Min value: ' + min); // 输出: Min value: -5

字符串的数组

let numbersStr = ['-5', '10', '-3', '15', '7'];

let numbers = numbersStr.map(num => +num);

let max = Math.max(...numbers);

let min = Math.min(...numbers);

console.log('Max value: ' + max); // 输出: Max value: 15

console.log('Min value: ' + min); // 输出: Min value: -5
