JavaScript: Check from two given integers whether one of them is 8 or their sum or difference is 8

JavaScript Basic: Exercise-40 with Solution

Check if Integer is 8 or Difference/Sum Equals 8

Write a JavaScript program to check from two given integers whether one of them is 8 or their sum or difference is 8.

This JavaScript program checks two given integers to see if one of them is 8 or if their sum or difference is 8. If any of these conditions are met, it returns true; otherwise, it returns false.

Visual Presentation:

Sample Solution:

JavaScript Code:

// Define a function named check8 with parameters x and y
function check8(x, y) {
  // Check if x or y is equal to 8
  if (x == 8 || y == 8) {
    // Return true if the condition is true
    return true;
  }

  // Check if the sum of x and y is equal to 8 or the absolute difference between x and y is equal to 8
  if (x + y == 8 || Math.abs(x - y) == 8) {
    // Return true if the condition is true
    return true;
  }

  // Return false if none of the conditions are met
  return false;
}

// Log the result of calling check8 with the arguments 7 and 8 to the console
console.log(check8(7, 8));

// Log the result of calling check8 with the arguments 16 and 8 to the console
console.log(check8(16, 8));

// Log the result of calling check8 with the arguments 24 and 32 to the console
console.log(check8(24, 32));

// Log the result of calling check8 with the arguments 17 and 18 to the console
console.log(check8(17, 18)); 

Output:

true
true
true
false

Flowchart:

ES6 Version:

// Define a function named check8 using arrow function syntax with parameters x and y
const check8 = (x, y) => {
  // Check if x or y is equal to 8
  if (x == 8 || y == 8) {
    return true;
  }

  // Check if the sum of x and y is equal to 8 or the absolute difference is equal to 8
  if (x + y == 8 || Math.abs(x - y) == 8) {
    return true;
  }

  // Return false if none of the conditions are met
  return false;
};

// Log the result of calling check8 with the arguments 7 and 8 to the console
console.log(check8(7, 8));

// Log the result of calling check8 with the arguments 16 and 8 to the console
console.log(check8(16, 8));

// Log the result of calling check8 with the arguments 24 and 32 to the console
console.log(check8(24, 32));

// Log the result of calling check8 with the arguments 17 and 18 to the console
console.log(check8(17, 18));

Previous: 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: 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.
