# JavaScript: Compute the absolute difference between a specified number and 19

## JavaScript Basic: Exercise-17 with Solution

Write a JavaScript program to compute the absolute difference between a specified number and 19. Returns triple the absolute difference if the specified number is greater than 19.

Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JavaScript program to compute the absolute difference between a specified number and 19.  Returns triple their absolute difference if the specified number is greater than 19.</title>
<body>

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

JavaScript Code:

``````function diff_num(n) {
if (n <= 19) {
return (19 - n);
}
else
{
return (n - 19) * 3;
}
}

console.log(diff_num(12));
console.log(diff_num(19));
console.log(diff_num(22));
```
```

Sample Output:

```7
0
9
```

Flowchart:

ES6 Version:

``````function diff_num(n) {
if (n <= 19) {
return (19 - n);
}
else
{
return (n - 19) * 3;
}
}

console.log(diff_num(12));
console.log(diff_num(19));
console.log(diff_num(22));
``````

## JavaScript: Tips of the Day

Example:

```const parseCookie = str =>
str
.split(';')
.map(v => v.split('='))
.reduce((acc, v) => {
acc[decodeURIComponent(v[0].trim())] = decodeURIComponent(v[1].trim());
return acc;
}, {});
console.log(parseCookie('foo=bar; equation=E%3Dmc%5E2')); // { foo: 'bar', equation: 'E=mc^2' }
```

Output:

```[object Object] {
equation: "E=mc^2",
foo: "bar"
}
```
