Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to check three given numbers, if the three numbers are same return 30 otherwise return 20 and if two numbers are same return 40.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function three_numbers(x, y, z) {
  if (x == y && y == z) {
    return 30;
  }

  if (x == y || y == z || z == x) {
    return 40;
  }

  return 20;
}
console.log(three_numbers(8, 8, 8));
console.log(three_numbers(8, 8, 18));
console.log(three_numbers(8, 7, 18));

Sample Output:

30
40
20

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".
