js计算多个数相加求和

const numbers = [1, 2, 3, 4, 5];let sum = 0;for (let i = 0; i <p><strong>2. 使用 reduce 方法</strong></p><pre class="brush:php;toolbar:false">const numbers = [1, 2, 3, 4, 5];const sum = numbers.reduce((acc, cur) =&gt; acc + cur, 0);console.log(sum); // 输出：15

const numbers = [1, 2, 3, 4, 5];let sum = 0;numbers.forEach((number) => {  sum += number;});console.log(sum); // 输出：15
