Sample Solution:

HTML Code:

<!DOCTYPE html>

</head>
<body>

</body>
</html>

JavaScript Code:

function check8(x, y) {
  if (x == 8 || y == 8) {
    return true;
  }

  if (x + y == 8 || Math.abs(x - y) == 8)
  {
    return true;
  }

  return false;
}

console.log(check8(7, 8));
console.log(check8(16, 8));
console.log(check8(24, 32));
console.log(check8(17, 18));

Sample Output:

true
true
true
false

Previous: Write a JavaScript program to compute the sum of the two given integers, If the sum is in the range 50..80 return 65 other wise return 80.
Next: Write a JavaScript program to check three given numbers, if the three numbers are same return 30 otherwise return 20 and if two numbers are same return 40.

JavaScript: Tips of the Day

Calculates the greatest common divisor between two or more numbers/arrays

Example:

const tips_gcd = (...arr) => {
  const gcd = (x, y) => (!y ? x : tips_gcd(y, x % y));
  return [...arr].reduce((p, q) => gcd(p, q));
};
console.log(tips_gcd(5, 25));
console.log(tips_gcd(...[8, 16, 32])); 

Output:

5
8
