JavaScript Basic: Exercise-106 with Solution

Write a JavaScript program to divide an integer by another integer as long as the result is an integer and return the result.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title> Divide an integer by another integer as long as the result is an integer and return the result</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function divide_digit(num, d) {
       if (d==1)
         return num;
       else
       {
      while (num % d === 0) {
        num /= d;
        }
    return num;
       }
}
console.log(divide_digit(-12, 2))
console.log(divide_digit(13, 2))
console.log(divide_digit(13, 1))

Sample Output:

-3
13
13

Flowchart:

ES6 Version:

function divide_digit(num, d) {
       if (d==1)
         return num;
       else
       {
      while (num % d === 0) {
        num /= d;
        }
    return num;
       }
}
console.log(divide_digit(-12, 2))
console.log(divide_digit(13, 2))
console.log(divide_digit(13, 1))

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());
