JavaScript: Divide an integer by another integer as long as the result is an integer and return the result

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

Converts a string to title case

Example:

const toTitleCase = str =>
  str
    .match(/[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+/g)
    .map(x => x.charAt(0).toUpperCase() + x.slice(1))
    .join(' ');
console.log(toTitleCase('some_database_field_name')); // 'Some Database Field Name'
console.log(toTitleCase('Some label that needs to be title-cased')); // 'Some Label That Needs To Be Title Cased'
console.log(toTitleCase('some-package-name')); // 'Some Package Name'
console.log(toTitleCase('some-mixed_string with spaces_underscores-and-hyphens')); // 'Some Mixed String With Spaces Underscores And Hyphens' 

Output:

"Some Database Field Name"
"Some Label That Needs To Be Title Cased"
"Some Package Name"
"Some Mixed String With Spaces Underscores And Hyphens"
