JavaScript Basic: Exercise-46 with Solution

Write a JavaScript program to check two given non-negative integers that whether one of the number (not both) is multiple of 7 or 11.

Pictorial Presentation:

JavaScript: Check from two given non-negative integers that whether one of the number is multiple of 7 or 11

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to check two given non-negative integers that whether one of the number (not both) is multiple of 7 or 11.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function valCheck (a, b) {
if (!((a % 7 == 0 || a % 11 == 0) && (b % 7 == 0 || b % 11 == 0))) {
return ((a % 7 == 0 || a % 11 == 0) || (b % 7 == 0 || b % 11 == 0));
}
else
return false;
}
console.log(valCheck(14, 21));
console.log(valCheck(14, 20));
console.log(valCheck(16, 20));

Sample Output:

false
true
false

Flowchart:

ES6 Version:

function valCheck (a, b) {
if (!((a % 7 == 0 || a % 11 == 0) && (b % 7 == 0 || b % 11 == 0))) {
return ((a % 7 == 0 || a % 11 == 0) || (b % 7 == 0 || b % 11 == 0));
}
else
return false;
}
console.log(valCheck(14, 21));
console.log(valCheck(14, 20));
console.log(valCheck(16, 20));

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());
