Below is my solution to the HackerRank "Simple Array Sum" challenge. In order to pass the tests, you'll need to iterate through the array of integers and sum them up. I chose to do this using the reduce
method. You'll then need to print the resulting sum to the console.
function main() {
let n = parseInt(readLine()),
arr = readLine().split(' ').map(Number),
sum = arr.reduce(function(acc, number) {
return acc + number;
}, 0);
console.log(sum);
return sum;
}
