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

Classes/function constructors

class Person {
  constructor() {
    this.name = 'Owen';
  }
}

Person = class AnotherPerson {
  constructor() {
    this.name = 'Eddie';
  }
};

const member = new Person();
console.log(member.name);

We can set classes equal to other classes/function constructors. In this case, we set Person equal to AnotherPerson. The name on this constructor is Eddie, so the name property on the new Person instance member is "Eddie".
