JavaScript Basic: Exercise-43 with Solution
Write a JavaScript program to check from three given numbers (non negative integers) that two or all of them have the same rightmost digit.
Pictorial Presentation:

Sample Solution:
HTML Code:
<!DOCTYPE html>
<html>
<head>
<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>
</head>
<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
Randomizes the order of the values of an array, returning a new array
Example:
const tips_shuffle = ([...arr]) => { let x = arr.length; while (x) { const i = Math.floor(Math.random() * x--); [arr[x], arr[i]] = [arr[i], arr[x]]; } return arr; }; const foo = [2, 4, 6]; console.log(tips_shuffle(foo));
Output:
[4, 2, 6]
