JavaScript Basic: Exercise-45 with Solution

Check if Integer is 15, or Sum/Difference is 15

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.

This JavaScript program evaluates two integer values to determine if either one is equal to 15 or if their sum or difference equals 15. If any of these conditions are met, it returns true; otherwise, it returns false.

Visual 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:

JavaScript Code:

// Define a function named test_number with parameters x and y
function test_number(x, y) {
    // Return true if x is equal to 15, y is equal to 15, the sum of x and y is equal to 15,
    // or the absolute difference between x and y is equal to 15; otherwise, return false.
    return (x === 15 || y === 15 || x + y === 15 || Math.abs(x - y) === 15);
}

// Log the result of calling test_number with the arguments 15 and 9 to the console
console.log(test_number(15, 9));

// Log the result of calling test_number with the arguments 25 and 15 to the console
console.log(test_number(25, 15));

// Log the result of calling test_number with the arguments 7 and 8 to the console
console.log(test_number(7, 8));

// Log the result of calling test_number with the arguments 25 and 10 to the console
console.log(test_number(25, 10));

// Log the result of calling test_number with the arguments 5 and 9 to the console
console.log(test_number(5, 9));

// Log the result of calling test_number with the arguments 7 and 9 to the console
console.log(test_number(7, 9));

// Log the result of calling test_number with the arguments 9 and 25 to the console
console.log(test_number(9, 25));

Output:

true
true
true
true
false
false
false

function test_number(x, y) {
    // Return true if x is equal to 15, y is equal to 15, the sum of x and y is equal to 15, or the absolute difference between x and y is equal to 15
    return (x === 15 || y === 15 || x + y === 15 || Math.abs(x - y) === 15);
}

// Log the result of calling test_number with the arguments 15 and 9 to the console
console.log(test_number(15, 9));

// Log the result of calling test_number with the arguments 25 and 15 to the console
console.log(test_number(25, 15));

// Log the result of calling test_number with the arguments 7 and 8 to the console
console.log(test_number(7, 8));

// Log the result of calling test_number with the arguments 25 and 10 to the console
console.log(test_number(25, 10));

// Log the result of calling test_number with the arguments 5 and 9 to the console
console.log(test_number(5, 9));

// Log the result of calling test_number with the arguments 7 and 9 to the console
console.log(test_number(7, 9));

// Log the result of calling test_number with the arguments 9 and 25 to the console
console.log(test_number(9, 25));
