JavaScript: Check two given numbers and return true if one of the number is 50 or if their sum is 50

JavaScript Basic: Exercise-18 with Solution

Write a JavaScript program to check a pair of numbers and return true if one of the numbers is 50 or if their sum is 50.

Pictorial Presentation:

Sample Solution:

JavaScript Code:

// Define a function named test50 that takes two parameters, x and y
function test50(x, y) {
  // Return true if x is equal to 50 or y is equal to 50 or the sum of x and y is equal to 50; otherwise, return false
  return ((x == 50 || y == 50) || (x + y == 50));
}

// Log the result of calling the test50 function with the arguments 50 and 50 to the console
console.log(test50(50, 50));

// Log the result of calling the test50 function with the arguments 20 and 50 to the console
console.log(test50(20, 50));

// Log the result of calling the test50 function with the arguments 20 and 20 to the console
console.log(test50(20, 20));

// Log the result of calling the test50 function with the arguments 20 and 30 to the console
console.log(test50(20, 30));

Output:

true
true
false
true

Flowchart:

ES6 Version:

// Using ES6 arrow function syntax to define the test50 function
const test50 = (x, y) => ((x === 50 || y === 50) || (x + y === 50));

// Log the result of calling the test50 function with the arguments 50 and 50 to the console
console.log(test50(50, 50));

// Log the result of calling the test50 function with the arguments 20 and 50 to the console
console.log(test50(20, 50));

// Log the result of calling the test50 function with the arguments 20 and 20 to the console
console.log(test50(20, 20));

// Log the result of calling the test50 function with the arguments 20 and 30 to the console
console.log(test50(20, 30));
