<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to check whether three given integer values are in the range 50..99 (inclusive). Return true if one or more of them are in the said range.</title>
</head>
<body>

</html>

JavaScript Code:

function check_three_nums(x, y, z) 
{
  return (x >= 50 && x <= 99) || (y >= 50 && y <= 99) || (z >= 50 && z <= 99);
}

console.log(check_three_nums(50, 90, 99));
console.log(check_three_nums(5, 9, 199));
console.log(check_three_nums(65, 89, 199));
console.log(check_three_nums(65, 9, 199));

Sample Output:

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
