## 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>

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:

## JavaScript: Tips of the Day

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"
