 # JavaScript: Get the largest even number from an array of integers

## JavaScript Basic: Exercise-126 with Solution

Write a JavaScript program to get the largest even number from an array of integers.

Pictorial Presentation: Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title> Get the largest even number from an array of integers</title>
<body>

</body>
</html>
```
```

JavaScript Code:

``````function max_even(arra) {

arra.sort((x, y) => y - x);

for (var i = 0; i < arra.length; i++) {
if (arra[i] % 2 == 0)
return arra[i];
}
}

console.log(max_even([20, 40, 200]));
console.log(max_even([20, 40, 200, 301]));
``````

Sample Output:

```200
200
```

Flowchart: ES6 Version:

``````function max_even(arra) {

arra.sort((x, y) => y - x);

for (let i = 0; i < arra.length; i++) {
if (arra[i] % 2 == 0)
return arra[i];
}
}

console.log(max_even([20, 40, 200]));
console.log(max_even([20, 40, 200, 301]));
``````

## 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".
