JS-函数封装数组求和案例

function array (d){
                let sum = 0 ;
                for (let i = 0; i < d.length; i++) {
                    sum += d[i];
                }
                return sum;
            }
            let arr2 = [1, 2, 6, 79, 23];
            array(arr2);
            console.log(array(arr2));
            let arr100= [ 1,852,963,4,852,1,5];
            array(arr100);
            console.log(array(arr100));
