JavaScript: Create the value of NOR of two given booleans

JavaScript Basic: Exercise-124 with Solution

Write a JavaScript program to create the NOR value of two given booleans.

Note: In boolean logic, logical nor or joint denial is a truth-functional operator which produces a result that is the negation of logical or. That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true - i.e. when both of p and q are false

Sample Example:

For x = true and y = false, the output should be logical_Nor(x, y) = false; For x = false and y = false, the output should be logical_Nor(x, y) = true.

Sample Solution:

JavaScript Code:

// Function to perform logical NOR operation
function test_logical_Nor(a, b) {
  return (!a && !b); // Returns true only if both a and b are false
}

// Testing logical NOR operation with different input values
console.log(test_logical_Nor(true, false));  // Output: false (logical NOR of true and false is false)
console.log(test_logical_Nor(false, false)); // Output: true (logical NOR of false and false is true)
console.log(test_logical_Nor(true, true));   // Output: false (logical NOR of true and true is false) 

Output:

false
true
false

Flowchart:

ES6 Version:

// ES6 function to perform logical NOR operation
const test_logical_Nor = (a, b) => {
  return (!a && !b); // Returns true only if both a and b are false
};

// Testing logical NOR operation with different input values
console.log(test_logical_Nor(true, false));  // Output: false (logical NOR of true and false is false)
console.log(test_logical_Nor(false, false)); // Output: true (logical NOR of false and false is true)
console.log(test_logical_Nor(true, true));   // Output: false (logical NOR of true and true is false)
