JavaScript Basic: Exercise-45 with Solution

Write a JavaScript program to check two given integer values and return true if one of the number is 15 or if their sum or difference is 15.

Pictorial Presentation:

JavaScript: Check two given integer values and return true if one of the number is 15 or if their sum or difference is 15

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to check two given integer values and return true if one of the number is 15 or if their sum or difference is 15.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function test_number(x, y) {
    return (x === 15 || y === 15 || x + y === 15 || Math.abs(x - y) === 15);
}

console.log(test_number(15, 9));
console.log(test_number(25, 15));
console.log(test_number(7, 8));
console.log(test_number(25, 10));
console.log(test_number(5, 9));
console.log(test_number(7, 9));
console.log(test_number(9, 25));

Sample Output:

true
true
true

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
