 # JavaScript: Check from two given integers whether one of them is 8 or their sum or difference is 8

## JavaScript Basic: Exercise-40 with Solution

Write a JavaScript program to check from two given integers whether one of them is 8 or their sum or difference is 8.

Pictorial Presentation: Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Write a JavaScript program to check from two given integers whether one of them is 8 or their sum or difference is 8.</title>
<body>

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

JavaScript Code:

``````function check8(x, y) {
if (x == 8 || y == 8) {
return true;
}

if (x + y == 8 || Math.abs(x - y) == 8)
{
return true;
}

return false;
}

console.log(check8(7, 8));
console.log(check8(16, 8));
console.log(check8(24, 32));
console.log(check8(17, 18));
```
```

Sample Output:

```true
true
true
false
```

Flowchart: ES6 Version:

``````function check8(x, y) {
if (x == 8 || y == 8) {
return true;
}

if (x + y == 8 || Math.abs(x - y) == 8)
{
return true;
}

return false;
}

console.log(check8(7, 8));
console.log(check8(16, 8));
console.log(check8(24, 32));
console.log(check8(17, 18));
``````

## JavaScript: Tips of the Day

Returns the sum of the powers of all the numbers from start to end (both inclusive)

Example:

```const sumPower = (end, power = 2, start = 1) =>
Array(end + 1 - start)
.fill(0)
.map((x, i) => (i + start) ** power)
.reduce((a, b) => a + b, 0);
console.log(sumPower(10)); // 385
console.log(sumPower(10, 3)); // 3025
console.log(sumPower(10, 3, 5)); // 2925
```

Output:

```385
3025
2925
```
