Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JavaScript program to check from three  given numbers (non negative integers) that two  or all of them have the same rightmost digit.</title>
<body>
</body>
</html>

JavaScript Code:

function same_last_digit(p, q, r) {
return (p % 10 === q % 10) ||
(p % 10 === r % 10) ||
(q % 10 === r % 10);

}

console.log(same_last_digit(22,32,42));
console.log(same_last_digit(102,302,2));
console.log(same_last_digit(20,22,45));

Sample Output:

true
true
false

Flowchart:

ES6 Version:

function same_last_digit(p, q, r) {
return (p % 10 === q % 10) ||
(p % 10 === r % 10) ||
(q % 10 === r % 10);

}

console.log(same_last_digit(22,32,42));
console.log(same_last_digit(102,302,2));
console.log(same_last_digit(20,22,45));

## JavaScript: Tips of the Day

Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters)

Example:

const isAnagram = (str1, str2) => {
const normalize = str =>
str
.toLowerCase()
.replace(/[^a-z0-9]/gi, '')
.split('')
.sort()
.join('');
return normalize(str1) === normalize(str2);
};
console.log(isAnagram('iceman', 'cinema')); // true

Output:

true
