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.

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

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]
