JavaScript Code:

function sortaSum(x, y) 
 {
  const sum_nums = x + y;
  if (sum_nums >= 50 && sum_nums <= 80) {
    return 65;
  }
  return 80;
}

console.log(sortaSum(30,20));
console.log(sortaSum(90,80));

Sample Output:

65

JavaScript: Tips of the Day

Returns the sum of the powers of all the numbers from start to end (both inclusive)

Example:

const sumPower = (end, power = 2, start = 1) =>
  Array(end + 1 - start)
    .fill(0)
    .map((x, i) => (i + start) ** power)
    .reduce((a, b) => a + b, 0);
console.log(sumPower(10)); // 385
console.log(sumPower(10, 3)); // 3025
console.log(sumPower(10, 3, 5)); // 2925 

Output:

385
3025
2925
