JavaScript Basic: Exercise-124 with Solution

Write a JavaScript program to create the value of NOR 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:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title> Create the value of NOR of two given booleans</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function test_logical_Nor(a, b) {
  return (!a && !b)
}
console.log(test_logical_Nor(true, false));
console.log(test_logical_Nor(false, false));
console.log(test_logical_Nor(true, true));

Sample Output:

false
true
false

Flowchart:

ES6 Version:

function test_logical_Nor(a, b) {
  return (!a && !b)
}
console.log(test_logical_Nor(true, false));
console.log(test_logical_Nor(false, false));
console.log(test_logical_Nor(true, true));

JavaScript: Tips of the Day

How to insert an item into an array at a specific index (JavaScript)?

What you want is the splice function on the native array object.

arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:

var arr = []; arr[0] = "Jani"; arr[1] = "Hege"; arr[2] = "Stale"; arr[3] = "Kai Jim"; arr[4] = "Borge"; console.log(arr.join()); arr.splice(2, 0, "Lene"); console.log(arr.join());
