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

JavaScript Basic: Exercise-45 with Solution

Write a JavaScript program that checks two integer values and returns true if either one 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
true
false
false
false

JavaScript: Tips of the Day

Assigns default values for all properties in an object that are undefined

Example:

const tips_defaults = (obj, ...defs) => Object.assign({}, obj, ...defs.reverse(), obj);
console.log(tips_defaults({ p: 1 }, { q: 2 }, { q: 6 }, { p: 3 }));

Output:

[object Object] {
  p: 1,
  q: 2
}
