JavaScript Basic: Exercise-88 with Solution

Write a JavaScript program to check whether two given integers are similar or not, if a given divisor divides both integers and it does not divide either.

Pictorial Presentation:

JavaScript: Check whether two given integers are similar or not.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>Check whether two given integers are similar or not</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function checking_numbers(x, y, divisor) {
  if(x % divisor === 0 && y % divisor === 0 || x % divisor !== 0 && y % divisor !==
    0) {
    return true;
  }
  return false;
}

console.log(checking_numbers(10, 25, 5))
console.log(checking_numbers(10, 20, 5))
console.log(checking_numbers(10, 20, 4))


Sample Output:

true
true
false

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"
