 # JavaScript: Check three given numbers, if the three numbers are same return 30 otherwise return 20 and if two numbers are same return 40

## JavaScript Basic: Exercise-41 with Solution

Write a 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.

Pictorial Presentation: Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<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>
<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
```

Flowchart: ES6 Version:

``````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));
``````

## 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".
