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 integers that whether a number is greater than or equal to 20 and less than one of the others.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function lessby20_others(x, y, z) 
{
return (x >= 20 && (x < y || x < z)) ||
(y >= 20 && (y < x || y < z)) ||
(z >= 20 && (z < y || z < x));
}
console.log(lessby20_others(23, 45, 10));
console.log(lessby20_others(23, 23, 10));
console.log(lessby20_others(21, 66, 75));

Sample Output:

true
false
true

Previous: Write a JavaScript program to check from three given numbers (non negative integers) that two or all of them have the same rightmost digit.
Next: Write a JavaScript program to check two given integer values and return true if one of the number is 15 or if their sum or difference is 15.

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".
