DESCRIPTION:
Complete the square sum function so that it squares each number passed into it and then sums the results together.
For example, for [1, 2, 2] it should return 9 because
function squareSum(numbers){
let sum=0;
for(let i =0; i < numbers.length; i++){
sum += numbers[i]**2;
}
return sum;
}
numbers[i]*numbers[i];로 해도 된다.
