## JavaScript Basic: Exercise-44 with Solution

Write a 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.

```
```

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));
```

## 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".
