Simple JavaScript/NodeJs solution:

function miniMaxSum(arr) { // Write your code here let min = arr[0]; let max = arr[0]; let totalArrSum = 0;

for (let i = 0; i < arr.length; i++) {
    totalArrSum += arr[i];
    if (arr[i] < min) {
        min = arr[i];
    }
    if (arr[i] > max) {
        max = arr[i];
    }
}

console.log(``${totalArrSum - max} $`{totalArrSum - min}`);

}
